Physical properties of trans-Neptunian object (143707) 2003 UY117 derived from stellar occultation and photometric observations
M. Kretlow, J. L. Ortiz, J. Desmars +49
Trans-Neptunian objects (TNOs) are considered to be among the most primitive objects in our Solar System. Knowledge of their primary physical properties is essential for understand…
The core collapse of a 16.5 M star
Amar Aryan, Shashi Bhushan Pandey, Rahul Gupta +2
We investigate the 1D stellar evolution of a 16.5 M zero-age main-sequence star having different initial rotations. Starting from the pre-main-sequence, the models evolve…
Prompt and afterglow analysis of the Fermi-LAT detected GRB 230812B
Amit K. Ror, S. B. Pandey, A. Aryan +2
Prompt emission of GRB 230812B stands out as one of the most luminous events observed by both the Fermi-GBM and LAT. Prompt emission spectral analysis (both time-integrated and res…
Combined search in dwarf spheroidal galaxies for branon dark matter annihilation signatures with the MAGIC Telescopes
T. Miener, D. Nieto, V. Gammaldi +2
One of the most pressing questions for modern physics is the nature of dark matter (DM). Several efforts have been made to model this elusive kind of matter. The largest fraction o…
Furiously Fast and Red: Sub-second Optical Flaring in V404 Cyg during the 2015 Outburst Peak
P. Gandhi, S. P. Littlefair, L. K. Hardy +25
We present observations of rapid (sub-second) optical flux variability in V404 Cyg during its 2015 June outburst. Simultaneous three-band observations with the ULTRACAM fast imager…
