Distance Measurements and Stellar Population Properties via Surface Brightness Fluctuations 
Alexander Fritz

Surface brightness fluctuations are one of the most powerful techniques to measure the distance and constrain the unresolved stellar content of extragalactic systems. This article gives a historical background, reviews the basic concepts, presents a broad sample of investigations and discusses possible selection effects, biases, and limitations of the method.

Cosmological Surveys with the Australian Square Kilometre Array Pathfinder 
A. R. Duffy, A. Moss and L. Staveley-Smith

This is a design study into using the Australian Square Kilometre Array Pathfinder full-sky low redshift neutral hydrogen survey, WALLABY, to measure the galaxy power spectrum. With 66 × 105 redshifts, WALLABY, when combined with Planck CMB data, will constrain the Dark Energy equation of state to 20%.

AMS Applications in Nuclear Astrophysics: New Results for 13C(n,γ)14C and 14N(n,p)14C 
A. Wallner, K. Buczak, I. Dillmann, J. Feige, F. Käppeler, G. Korschinek, C. Lederer, A. Mengoni, U. Ott, M. Paul, G. Schätzel, P. Steier and H. P. Trautvetter

The complementary technique of neutron activation and subsequent accelerator mass spectrometry (AMS) measurement was for the first time applied to studying 14C production from 13C(n,γ) and 14N(n,p). New data for these neutron poisons obtained for neutron energies between 25 and 178 keV are slightly lower than previous results and evaluations suggest.

Trapped and Escaping Orbits in an Axially Symmetric Galactic-Type Potential 
Euaggelos E. Zotos

In this article, we investigate the behavior of orbits in an axially symmetric galactic-type potential. Our numerical calculations suggest that in this potential, there are two kinds of orbits: (i) escaping and (ii) trapped, which do not escape at all. Among the chaotic orbits, there are orbits that escape fast and also orbits that remain trapped for vast time intervals.

A Coronal Jet Ejection from a Sunspot Light Bridge 
S. Liu

A coronal jet ejection from a sunspot light bridge is presented. It is confirmed that the jet has its root near the light bridge. This suggests that the jet may be a result of reconnection between the main sunspot and the light bridge.

Planet-Induced Emission Enhancements in HD 179949: Results from McDonald Observations 
L. Gurdemir, S. Redfield and M. Cuntz

We monitored the Ca ii lines of HD 179949 at the McDonald Observatory to observe planet induced emission (PIE) as an effect of star–planet interaction. Detailed statistical analysis revealed fluctuations in the Ca ii K core consistent with previous studies. We also confirmed the reality and temporal evolution of the phase shift of the maximum of star–planet interaction.

High-Level Magnetic Activity on a Low-Mass Close Binary: GSC 02038-0293 
H. A. Dal, E. Sipahi and O. Özdarcan

We analysed GSC 02038-00293's light curve and modelled its light variation at out-of-eclipse phases using the phoebe and spotmodel programs. The analyses indicated that there are two migrating active longitudes for the active component. The amplitude at out-of-eclipse phases varies in a sinusoidal way with a period of 8.9 yr, while the mean brightness is dramatically decreasing.

The Search for Supernova-Produced Radionuclides in Terrestrial Deep-Sea Archives 
J. Feige, A. Wallner, S. R. Winkler, S. Merchel, L. K. Fifield, G. Korschinek, G. Rugel and D. Breitschwerdt

We estimate the intensity of possible supernova-produced radionuclides 26Al, 53Mn, 60Fe, and the pure r-process element 244Pu in two marine sediment cores from the Indian Ocean. Detecting these radionuclides with accelerator mass spectrometry allows us to link the signal to a supernova event in the solar vicinity ~2 Myr ago.

Feature Detection in Radio Astronomy using the Circle Hough Transform 
C. Hollitt and M. Johnston-Hollitt

Existing telescopes rely on human expertise to reduce raw data and then analyse the images for non-pointlike objects; however, the next generation of radio telescopes will make this infeasible. We explore the Circle Hough Transform as a detection method on a sample of different extended circular or arc-like astronomical objects.

Neutron Stars From Young Nearby Associations: The Origin of RX J1605.3+3249 
N. Tetzlaff, J. G. Schmidt, M. M. Hohle and R. Neuhäuser

Many neutron stars and runaway stars apparently come from the same regions on the sky. This suggests that they share the same birth places. To identify these birth places, we attempt to find NS-runaway pairs that could be possible former companions that were disrupted in a supernova. If nearby and recent, the remains are still visible in emission of radioisotopes.

Transformations from WISE to 2MASS, SDSS and BVI Photometric Systems: II. Transformation Equations for Red-Clump Stars 
S. Bilir, S. Karaali, N. D. Daǧtekin, Ö. Önal, S. Ak, T. Ak and A. Cabrera-Lavers

We present colour transformations for the conversion of WISE magnitudes to the BVIc, gri, and JHKs photometric systems for red clump stars. The selected samples were used to obtain metallicity-dependent and free-of-metallicity transformations. These transformations can be used in the studies of the Galactic structure.

Near-Infrared Properties of Type Ia Supernovae 
M. M. Phillips

The photometric properties of Type Ia supernovae in the near-infrared from observations made over the last 30 years are reviewed. The data reveal considerable homogeneity, but also some fascinating differences. For all but the fastest declining objects, Type Ia supernovae are essentially perfect standard candles in the near-infrared.

New Attempts to Understand Nanodiamond Stardust 
U. Ott, A. Besmehn, K. Farouqi, O. Hallmann, P. Hoppe, K.-L. Kratz, K. Melber and A. Wallner

No evidence was found in nanodiamond stardust for the former presence of extinct 26Al or 44Ti. Observed overabundances of r-process-only 198Pt are in line with previously found excesses of heavy Xe and Te isotopes. As an alternative to dedicated scenarios, we have explored the r-process as a possible explanation.

Comparison of Potential ASKAP Hi Survey Source Finders 
A. Popping, R. Jurek, T. Westmeier, P. Serra, L. Flöer, M. Meyer and B. Koribalski

The large size of the ASKAP Hi surveys DINGO and WALLABY necessitates automated 3D source finding. Here we present a comparison of the performance of five different methods of automated source finding. These source finders are duchamp, gamma-finder, a cnhi finder, a 2d–1d wavelet reconstruction finder and a sigma clipping method (s+c finder).

Using Negative Detections to Estimate Source-Finder Reliability 
P. Serra, R. Jurek and L. Flöer

We discuss a method to determine the reliability of source finders within the context of upcoming Hi surveys. Assuming that the noise is symmetric and that real sources have positive total flux, we use sources with negative flux to assign to each positive detection a probability of being real.

Type-Ia Supernova Rates and the Progenitor Problem: A Review 
D. Maoz and F. Mannucci

The identity of the progenitors of type-Ia supernovae (SNe Ia) is a major puzzle. SN Ia rates are providing new clues, through the delay-time distribution (DTD) of these events. Recent measurements and analyses point to a ~t–1 DTD, suggesting that at least some SNe Ia result from double white dwarf mergers.

Basic Testing of the DUCHAMP Source Finder 
T. Westmeier, A. Popping and P. Serra

This paper discusses the results of basic source finding tests with the duchamp source finder on different source models. We find duchamp to be a powerful source finder, capable of reliably detecting sources down to low signal-to-noise ratios. duchamp's measurements of basic source parameters, however, are affected by systematic errors.

Maser Source-Finding Methods in HOPS 
A. J. Walsh, C. Purcell, S. Longmore, C. H. Jordan and V. Lowe

We have compared duchamp and manual identification methods for identifying masers in the Galactic plane survey HOPS. We find noise in the data is the limiting factor determining efficiency of both methods. duchamp may be useful for very large datasets, but the manual method is quicker for smaller datasets.

The Completeness and Reliability of Threshold and False-discovery Rate Source Extraction Algorithms for Compact Continuum Sources 
M. T. Huynh, A. Hopkins, R. Norris, P. Hancock, T. Murphy, R. Jurek and M. Whiting

The EMU survey with ASKAP aims to utilise an automated source identification and measurement approach that is demonstrably optimal. A key stage in source extraction methods is the background estimation and the choice of a threshold high enough to reject false sources, yet not so high that the catalogues are significantly incomplete. In this analysis, we present results from testing the SExtractor, Selavy (Duchamp), and sfind source extraction tools on simulated radio continuum data.

We have developed a method for simultaneously finding and fitting HI absorption lines in radio data by using multi-nested sampling, a Bayesian Monte Carlo algorithm. The method is tested on a simulated ASKAP data cube, and is shown to be produce reliable detections in low signal-to-noise data.

Galaxies on Sub-Galactic Scales 
Helmut Jerjen

Large-scale imaging surveys have been instrumental in finding the least luminous galaxies, uncovering inconsistencies between the CDM paradigm and galaxy properties, and reopening the debate about the building block scenario for the Milky Way. Progress in the field is discussed and attention drawn to future initiatives aimed at better understanding the phenomenon of 'ultra-faint dwarf galaxy'.

A Model for Contact Binary EP Andromedae 
Davood Manzoori
pp. 1-11

In this work, the solution of the standard V light curve of EP And, an over contact binary system, was obtained using the phoebe program. The structure and evolutionary status of the system is discussed. Times of minima data (‘O–C curve’) were analyzed. It was found that a third body with a period of 41.20 yr and mass 0.15 Msun is orbiting around the system. Also, a modulating period of an 11.72-yr cycle along with a relative period increase of were obtained, which were attributed to the magnetic activity cycle and the mass transfer with rate between the components, respectively.

 
  
 


 
On the Estimation of Atmospheric Aerosol Extinction Parameters from Measurements in the Johnson–Cousins Photometric System 
F. Sánchez-Bajo and D. Rodríguez-Estecha Álvarez
pp. 12-19

A procedure to estimate the aerosol extinction parameters of Angstrom’s formula using data taken with broadband filters is presented. The method is based on the determination of the equivalent mean wavelength monochromatic magnitudes from the heterochromatic ones using an iterative approach, correcting subsequently the water-vapour extinction in the longer-wavelength filters.

 
  
 


 
Stark Width Regularities within Neutral Calcium Spectral Series  
I. Tapalaga, I. P. Dojčinović, M. K. Milosavljević and J. Purić
pp. 20-28

Electron and proton impact Stark width dependences on the upper level ionization potential within neutral calcium spectral series were studied. The emphasis is on the term structure and temperature influence on these dependences. Using these dependences, predictions were made for lines not being measured experimentally or calculated theoretically until now.

 
  
 


 
Medium-Resolution s-process Element Survey of 47 Tuc Giant Stars

The Nature of the Light Variation of the Unique Binary DK CVn 
H. A. Dal, E. Sipahi and O. Özdarcan
pp. 54-65

We observed DK CVn and analysed the BVR light curves with phoebe v0.31a software. Several flares were detected and modelled by the OPEA. The model parameters demonstrated that the flares are the same as those of UV Ceti stars. This study reveals that DK CVn should be a chromospherically active binary star.

A Sky-Subtraction Algorithm for LAMOST Using Two-Dimensional Sky-Background Modeling 
J. Zhu and Z. Ye
pp. 78-85

A novel sky-subtraction algorithm is proposed for the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) based on two-dimensional sky-background modeling. Sky-subtraction can now be performed as an earlier step, before the spectrum extraction. Experiments based on LAMOST are presented to demonstrate the effectiveness of the proposed method.
