Type IIb Supernova Progenitors in 3D: Variability and Episodic Mass Loss revealed by Radiation-Hydrodynamics Simulations

Posted by klaurent UCSB

Kavli Affiliate: Lars Bildsten | First 5 Authors: Jared A. Goldberg, Jared A. Goldberg, , , | Summary: We present the first 3D Radiation-Hydrodynamics simulations of partially-stripped ($M_mathrmcoresim10M_odot$, $M_mathrmenvsim0.1-1M_odot$) Yellow Supergiant ($Lsim10^5$, $T_mathrmeffapprox5000-8000$K) envelopes, constructed with Athena++. These envelope models represent the progenitors of Type IIb supernovae (SNe-IIb), which have lost a substantial fraction of […]

ATLAS: A Self-Supervised and Cross-Stage Netlist Power Model for Fine-Grained Time-Based Layout Power Analysis

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Wenkai Li, Wenkai Li, , , | Summary: Accurate power prediction in VLSI design is crucial for effective power optimization, especially as designs get transformed from gate-level netlist to layout stages. However, traditional accurate power simulation requires time-consuming back-end processing and simulation steps, which significantly impede design […]

Long term variability of Cygnus X-1. IX. A spectral-timing comparison of Cygnus X-1 and MAXI J1820+070 in the hard state

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Arkadip Basak, Arkadip Basak, , , | Summary: Cygnus X-1 is a persistent, high-mass black hole X-ray binary (BHXRB) which in the hard state shows many similar properties to transient BHXRBs, along with intriguing differences, such as the lack of quasi-periodic oscillations. Here, we compare for the […]

High-Energy Neutrinos from Cosmic-Ray Scatterings with Supernova Neutrinos

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Gonzalo Herrera, Gonzalo Herrera, , , | Summary: Cosmic rays scattering with neutrinos produced in supernovae induce a flux of supernova neutrinos boosted to high energies. We calculate the neutrino flux arising from this new mechanism in environments with large cosmic-ray and supernova densities, such as some […]
