Arp 202: a TDG formed in a parent's extended dark matter halo?
T. C. Scott, P. Lagos, S. Ramya +6
We report on H + [NII] imaging of the Arp 202 interacting pair and its tidal dwarf galaxy (TDG) candidate as well as a GMOS long slit spectrum from the TDG candidate, observed w…
Evidence for Dynamically Driven Formation of the GW170817 Neutron Star Binary in NGC 4993
A. Palmese, W. Hartley, F. Tarsitano +89
We present a study of NGC 4993, the host galaxy of the GW170817 gravitational wave event, the GRB170817A short gamma-ray burst (sGRB) and the AT2017gfo kilonova. We use Dark Energy…
ALMA and GMRT constraints on the off-axis gamma-ray burst 170817A from the binary neutron star merger GW170817
Sam Kim, Steve Schulze, Lekshmi Resmi +31
Binary neutron-star mergers (BNSMs) are among the most readily detectable gravitational-wave (GW) sources with LIGO. They are also thought to produce short -ray bursts (SGRBs),…
Exploring the optical behaviour of a type Iax supernova SN 2014dt
Mridweeka Singh, Kuntal Misra, D. K. Sahu +9
We present optical photometric (upto 410 days since ) and spectroscopic (upto 157 days since ) observations of a Type Iax supernova (SN) 2014dt lo…
Rates of Short-GRB afterglows in association with Binary Neutron Star mergers
M. Saleem, Archana Pai, Kuntal Misra +2
Assuming all binary Neutron Star mergers produce Short Gamma Ray Bursts (SGRBs), we combine the merger rates of binary Neutron Stars (BNS) from population synthesis studies, the se…
Exploring Short-GRB afterglow parameter space for observations in coincidence with gravitational waves
M. Saleem, L. Resmi, Kuntal Misra +2
Short duration Gamma Ray Bursts(SGRB) and their afterglows are among the most promising electro-magnetic (EM) counterparts of Neutron Star (NS) mergers. The afterglow emission is b…
X-Ray Superflares on CC Eri
Subhajeet Karmakar, J. C. Pandey, V. S. Airapetian +1
We present an in-depth study of two superflares (F1 and F2) detected on an active binary star CC Eridani by the Swift observatory. These superflares triggered the Burst Alert Teles…
The properties of GRB 120923A at a spectroscopic redshift of z=7.8
N. R. Tanvir, T. Laskar, A. J. Levan +37
Gamma-ray bursts (GRBs) are powerful probes of early stars and galaxies, during and potentially even before the era of reionization. Although the number of GRBs identified at z>6 r…
