Unveiling diverse nature of core collapse supernovae
Amar Aryan
Core-collapse supernovae (CCSNe) are catastrophic astrophysical phenomena that occur during the last evolutionary stages of massive stars having initial masses of around 8 M$_{\odo…
Revealing characteristics of dark GRB 150309A: dust extinguished or high-z?
A. J. Castro-Tirado, Rahul Gupta, S. B. Pandey +28
Dark GRBs constitute a significant fraction of the GRB population. In this paper, we present the multiwavelength analysis of an intense two-episodic GRB 150309A observed early on t…
Recent observations of peculiar Gamma-ray bursts using 3.6 m Devasthal Optical Telescope (DOT)
Rahul Gupta, S. B. Pandey, Amit K. Ror +2
India has been actively involved in the follow-up observations of optical afterglows of gamma-ray bursts (GRBs) for more than two decades, using the country's meter-class facilitie…
Evolution and Final Fates of a Rotating 25 M Pop III star
Amar Aryan, Shashi Bhushan Pandey, Rahul Gupta +2
In this proceeding, we present the 1-dimensional stellar evolution of two rotating population III (Pop III) star models, each having a mass of 25 M at the zero-age main-s…
4K4K CCD Imager for the 3.6m DOT: Recent up-gradations and results
S. B. Pandey, Amit Kumar, B. K. Reddy +6
The 4K4K CCD Imager is the first light instrument for the 3.6m Devasthal Optical Telescope and is producing broad-band imaging observations of many Galactic and extra-galac…
Evolution of Rotating 25 M Population III star: Physical Properties and Resulting Supernovae
Amar Aryan, Shashi Bhushan Pandey, Rahul Gupta +1
In this Letter, we report the outcomes of 1-D modelling of a rotating 25 M zero-age main-sequence Population III star up to the stage of the onset of core collapse. Rapid…
