Self-consistent 3D Supernova Models From -7 Minutes to +7 Seconds: a 1-bethe Explosion of a ~19 Solar-mass Progenitor
R. Bollig, N. Yadav, D. Kresse +3
To date, modern three-dimensional (3D) supernova (SN) simulations have not demonstrated that explosion energies of 10^{51} erg (=1 bethe = 1B) or more are possible for neutrino-dri…
Large-Scale Mixing in a Violent Oxygen-Neon Shell Merger Prior to a Core-Collapse Supernova
Naveen Yadav, Bernhard Müller, Hans Thomas Janka +2
We present a seven-minute long -3D simulation of a shell merger event in a non-rotating supernova progenitor before the onset of gravitational collapse. The k…
Low frequency radio observations of SN 2011dh and the evolution of its post-shock plasma properties
Naveen Yadav, Alak Ray, Sayan Chakraborti
We present late time, low frequency observations of SN 2011dh made using the Giant Metrewave Radio Telescope (GMRT). Our observations at , and $1280\ \…
How multiple supernovae overlap to form superbubbles
Naveen Yadav, Dipanjan Mukherjee, Prateek Sharma +1
We explore the formation of superbubbles through energy deposition by multiple supernovae (SNe) in a uniform medium. We use total energy conserving, 3-D hydrodynamic simulations to…
A Missing-Link in the Supernova-GRB Connection: The Case of SN 2012ap
Sayan Chakraborti, Alicia Soderberg, Laura Chomiuk +50
Gamma Ray Bursts (GRBs) are characterized by ultra-relativistic outflows, while supernovae are generally characterized by non-relativistic ejecta. GRB afterglows decelerate rapidly…
Electron Cooling in a Young Radio Supernova: SN 2012aw
Naveen Yadav, Alak Ray, Sayan Chakraborti +8
We present the radio observations and modeling of an optically bright Type II-P supernova (SN), SN 2012aw which exploded in the nearby galaxy Messier 95 (M95) at a distance of $10\…
The progenitor of SN 2011ja: Clues from circumstellar interaction
Sayan Chakraborti, Alak Ray, Randall Smith +7
Massive stars, possibly red supergiants, which retain extended hydrogen envelopes until core collapse, produce Type II Plateau (IIP) supernovae. The ejecta from these explosions sh…
X-Ray emission from SN 2004dj: A Tale of Two Shocks
Sayan Chakraborti, Naveen Yadav, Alak Ray +2
Type IIP (Plateau) Supernovae are the most commonly observed variety of core collapse events. They have been detected in a wide range of wavelengths from radio, through optical to…
Radio Detection of Green Peas: Implications for Magnetic Fields in Young Galaxies
Sayan Chakraborti, Naveen Yadav, Carolin Cardamone +1
Green Peas are a new class of young, emission line galaxies that were discovered by citizen volunteers in the Galaxy Zoo project. Their low stellar mass, low metallicity and very h…
