Far-Ultraviolet to Near-Infrared Observations of SN 2023ixf: A high energy explosion engulfed in complex circumstellar material
Rishabh Singh Teja, Avinash Singh, Judhajeet Basu +13
We present early-phase panchromatic photometric and spectroscopic coverage spanning far-ultraviolet (FUV) to the near-infrared (NIR) regime of the nearest hydrogen-rich core-collap…
Science with the Daksha High Energy Transients Mission
Varun Bhalerao, Disha Sawant, Archana Pai +72
We present the science case for the proposed Daksha high energy transients mission. Daksha will comprise of two satellites covering the entire sky from 1~keV to ~MeV. The prima…
Optical studies of a bright Type Iax supernova SN 2020rea
Mridweeka Singh, Kuntal Misra, Devendra K. Sahu +14
We present optical photometric and spectroscopic analysis of a Type Iax supernova (SN) 2020rea situated at the brighter luminosity end of Type Iax supernovae (SNe). The light curve…
GROWTH on S190426c II: GROWTH-India Telescope search for an optical counterpart with a custom image reduction and candidate vetting pipeline
Harsh Kumar, Varun Bhalerao, G. C. Anupama +17
S190426c / GW190426_152155 was the first probable neutron star - black hole merger candidate detected by the LIGO-Virgo Collaboration. We undertook a tiled search for optical count…
Can the violent merger of white dwarfs explain the slowest declining Type Ia supernova SN 2011aa?
Anirban Dutta, G C Anupama, N K Chakradhari +1
We present optical observations and Monte Carlo radiative transfer modeling of the Type Ia supernova SN 2011aa. With a of mag and a peak magnitude $M_…
India's first robotic eye for time domain astrophysics: the GROWTH-India telescope
Harsh Kumar, Varun Bhalerao, G. C. Anupama +35
We present the design and performance of the GROWTH-India telescope, a 0.7 m robotic telescope dedicated to time-domain astronomy. The telescope is equipped with a 4k back-illumina…
Study of Complex Absorption and Reflection in a Unique Intermediate Polar Paloma
Anirban Dutta, Vikram Rana
We present the broadband (0.3-40.0 keV) X-ray analysis of a unique intermediate polar Paloma using simultaneous data from XMM-Newton and NuSTAR observatories. The X-ray power spect…
The long-active afterglow of GRB 210204A: Detection of the most delayed flares in a Gamma-Ray Burst
Harsh Kumar, Rahul Gupta, Divita Saraogi +22
We present results from extensive broadband follow-up of GRB 210204A over the period of thirty days. We detect optical flares in the afterglow at 7.6 x 10^5 s and 1.1 x 10^6 s afte…
A broadband X-ray study of the asynchronous polar: CD Ind
Anirban Dutta, Vikram Rana
A simultaneous broadband analysis of X-ray data obtained with XMM-Newton and NuSTAR observatories for the asynchronous polar source CD Ind is presented. The spin folded lightcurve…
