KIC 11401845: An Eclipsing Binary with Multiperiodic Pulsations and Light Travel Time
Jae Woo Lee, Kyeongsoo Hong, Seung-Lee Kim +1
We report the photometry of KIC 11401845 displaying multiperiodic pulsations, superimposed on binary effects. Light-curve synthesis represents that the binary star i…
Massive Galaxies are Larger in Dense Environments: Environmental Dependence of Mass-Size Relation of Early-Type Galaxies
Yongmin Yoon, Myungshin Im, Jae-Woo Kim
Under the cold dark matter (CDM) cosmological models, massive galaxies are expected to be larger in denser environments through frequent hierarchical mergers with other gala…

A. Raj, R. K. Das, F. M. Walter
We present optical spectrophotometric and near-infrared (NIR) photometric observations of the nova V2676 Oph covering the period from 2012 March 29 through 2015 May 8. The optical…
Polarization of Rayleigh scattered Lyα in active galactic nuclei
Seok-Jun Chang, Hee-Won Lee, Yujin Yang
The unification scheme of active galactic nuclei (AGNs) invokes an optically thick molecular torus component hiding the broad emission line region. Assuming the presence of a thick…
Pre-eruption Oscillations in Thin and Long Features in a Quiescent Filament
Anand D. Joshi, Yoichiro Hanaoka, Yoshinori Suematsu +3
We investigate the eruption of a quiescent filament located close to an active region. Large-scale activation was observed in only half of the filament in the form of pre-eruption…
To the Edge of M87 and Beyond: Spectroscopy of Intracluster Globular Clusters and Ultra Compact Dwarfs in the Virgo Cluster

Angular Momentum of Dwarf Galaxies
Kirsty M. Butler, Danail Obreschkow, Se-Heon Oh
We present measurements of baryonic mass Mb and specific angular momentum (sAM) jb in 14 rotating dwarf Irregular (dIrr) galaxies from the LITTLE THINGS sample. These measurements,…
Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
Astrochemical Properties of Planck Cold Clumps
Ken'ichi Tatematsu, Tie Liu, Satoshi Ohashi +25
We observed thirteen Planck cold clumps with the James Clerk Maxwell Telescope/SCUBA-2 and with the Nobeyama 45 m radio telescope. The NH distribution obtained with the Nob…
Metal-Rich SX Phe stars in the Kepler Field
James M. Nemec, Luis A. Balona, Simon J. Murphy +2
A spectroscopic and photometric analysis has been carried out for thirty-two candidate SX_Phe variable blue straggler stars in the Kepler-field (Balona & Nemec 2012). Radial veloci…
Space Telescope and Optical Reverberation Mapping Project VI: reverberating Disk Models for NGC 5548
D. Starkey, Keith Horne, M. M. Fausnaugh +90
We conduct a multiwavelength continuum variability study of the Seyfert 1 galaxy NGC 5548 to investigate the temperature structure of its accretion disk. The 19 overlapping continu…
Differences between radio-loud and radio-quiet gamma-ray pulsars as revealed by Fermi
C. Y. Hui, Jongsu Lee, J. Takata +2
By comparing the properties of non-recycled radio-loud ray pulsars and radio-quiet ray pulsars, we have searched for the differences between these two populations. We found…
The SAMI Galaxy Survey: Revisiting Galaxy Classification Through High-Order Stellar Kinematics
Jesse van de Sande, Joss Bland-Hawthorn, Lisa M. R. Fogarty +36
Recent cosmological hydrodynamical simulations suggest that integral field spectroscopy can connect the high-order stellar kinematic moments h3 (~skewness) and h4 (~kurtosis) in ga…
Discovery of five low luminosity active galactic nuclei at the centre of the Perseus cluster
