Exploring the multi-wavelength properties of the high energetic event ZTF20abbiixp/GRB 200524A: from prompt emission to afterglow
A. Ghosh, Dimple, K. Misra +32
We conducted a comprehensive multi-wavelength analysis of a high energetic long-duration ZTF20abbiixp / GRB~200524A detected by \textit{Fermi} Gamma Ray Burst Monitor (GBM). Our st…
Photometric and Spectroscopic Studies of Type Ic Supernovae SN 2020akf and SN 2021mxx
Mulchand Kurre, K. R. Sahu, Shrutika Tiwari +8
We present a comprehensive analysis of optical photometry and medium-resolution spectroscopy for Type Ic supernovae (SNe) SN 2020akf and SN 2021mxx. Our study covers the evolution…
Modeling the late time merger ejecta emission in short Gamma Ray Bursts
Ankur Ghosh, Kuntal Misra, C. S. Vaishnava +5
The short Gamma Ray Bursts (GRBs) are the aftermath of the merger of binary compact objects (neutron star -- neutron star or neutron star -- black hole systems). With the simultane…
Weak secondary cyclotron line in eclipsing High Mass X-ray Binary Cen X-3
Pravat Dangal, Ranjeev Misra, Nand Kumar Chakradhari +1
We report the time resolved spectroscopy result from two observations of Cen X-3, over one binary orbit with ASTROSAT and two binary orbit with NuSTAR. NuSTAR covered two intensity…
Type Ia supernovae SN 2013bz, PSN J0910+5003 and ASASSN-16ex: similar to 09dc-like?
S. Tiwari, N. K. Chakradhari, D. K. Sahu +3
We present optical photometric and spectroscopic studies of three supernovae (SNe) SN 2013bz, PSN J0910+5003 and ASASSN-16ex. UV-optical photometric data of ASASSN-16ex obtained wi…
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_…
Search for merger ejecta emission from late time radio observations of short GRBs using GMRT
Ankur Ghosh, C. S. Vaishnava, L. Resmi +4
Short gamma-ray bursts (GRBs) are the aftermath of compact binary mergers involving neutron stars. If the merger remnant is a millisecond magnetar instead of a black hole, a signif…
Quest for the upcoming periastron passage of an episodic dust maker and particle accelerating colliding wind binary: WR 125
Bharti Arora, J. C. Pandey, M. De Becker +4
We have carried out a long term infrared and X-ray investigation of the colliding wind binary WR 125 (WC7+O9III). The source was monitored using AstroSat-Soft X-ray Telescope and T…
Observational properties of a Type Ib Supernova MASTER OT J120451.50+265946.6 in NGC 4080
Mridweeka Singh, Kuntal Misra, D. K. Sahu +12
MASTER OT J120451.50+265946.6 (M12045), discovered by the MASTER Global Robotic Net, is a Type Ib supernova (SN) that exploded in NGC 4080. We present the {\it BVRI} photometric an…
Highly reddened type Ia supernova SN 2004ab: another case of anomalous extinction
N. K. Chakradhari, D. K. Sahu, G. C. Anupama +1
We present optical photometric and spectroscopic results of supernova SN 2004ab, a highly reddened normal type Ia supernova. The total reddening is estimated as = 1.70 $\p…
