Core-collapse supernovae are exploding massive stars and the next Galactic event will be one of the most interesting astronomical events of the century. After the collapse of a star's core, a so-called proto-neutron star (PNS) is formed, heating the star from the inside and creating a shock wave. It is believed that the majority of the gravitational-wave (GW) emission comes from PNS. The GW...
The astrophysical origin of heavy elements in the universe synthesised through the rapid neutron capture process (r-process) remains an open question, with several compact object environments such as neutron star mergers, collapsars, and magnetorotational supernovae proposed as potential sites. Systems involving accreting black holes and surrounding disks are particularly promising, as they...
Core-collapse supernovae are among the most energetic explosions in the universe. Their evolution is shaped by hydrodynamics, neutrino transport, and magnetic fields at work in the first seconds after collapse. We investigate these processes through 3D simulations of an extremely compact 39 Msun progenitor using the FLASH M1 magnetohydrodynamics code. Our study explores three models – a...
Gamma-ray bursts are one of the most energetic phenomena in the Universe. The collapsar model is the most widely accepted model for explaining long gamma-ray bursts. This model proposes that cores of massive stars with sufficient angular momentum collapse to black holes, while the stellar envelope starts to fall onto the newly born object. We performed three-dimensional GRMHD simulations of...
Core-collapse supernovae (CCSNe) are among the most energetic astrophysical phenomena. The next Galactic CCSN will be a landmark event and Gravitational Waves (GWs) from this CCSN will offer an unique opportunity to study the explosion dynamics in detail. In this poster, we will present the development of a method for the model-independent Coherent WaveBurst (cWB) algorithm to estimate GW...
Core-collapse supernovae (CCSN) are one of the most violent and energetic astronomical processes in the Universe. The next Galactic supernova can offer us an exceptional opportunity to delve deep into the explosion mechanism through gravitational waves (GWs) emission. Theoretical developments in CCSN modeling hint at the variation of GW signature with respect to the source angle orientation....
The generation of synthetic gravitational wave signals from core-collapse supernovae can provide a valuable tool for data augmentation in machine learning pipelines, especially for the training of detection and classification algorithms. These waveforms encode critical astrophysical information, such as the ratio of rotational kinetic to gravitational potential energy at bounce, pre-collapse...
Core collapse supernovae (CCSNe) are the explosive deaths of massive stars, followed by the formation of a proto-neutron star. Gravitational wave signals from these extremely compact objects can simultaneously inform macroscopic and microscopic physics, ranging from modeling what powers supernovae to constraining the nuclear equation of state. As the inner core of the collapsing star becomes...
Core-collapse supernovae (CCSNe) are exploding massive stars and the next Galactic event will be one of the most interesting astronomical events of the century. If the nearby CCSN will be strong enough and the light won't be obscured by the Galactic dust then it may be visible in the sky. If gravitational waves are detected, we will be able to even listen to this explosion. The sounds of...
Core-collapse supernovae (CCSNe) are exploding massive stars and the next Galactic event will be one of the most interesting astronomical events of the century. While these events are violent, the gravitational field is still relatively weak. Unlike the compact binaries with strong field regime where gravitational waveforms are given as spherical-harmonic modes in the Newman-Person formalism....
The traditional CCSN search method relies on coherence information between multiple gravitational wave detectors to identify candidate events. This requirement reduces the effective lifetime of the search, as it excludes periods when only a single detector is operational. To address this limitation, we present a machine learning (ML)-based framework designed to enable single-detector detection...
Core-collapse supernova in the Milky Way will be one of the most interesting astronomical events of the century. As the massive core suddenly collapses a huge number of neutrinos is produced. Around a hundred milliseconds after the collapse the asymmetry of a supernova evolves through a Ledoux convection. It is believed that it marks the beginning of an efficient emission of gravitational...
Core-collapse supernova (CCSN) marks the final stage of massive stars ($M>8M_{\odot}$) entering in a violent and energetic explosion process that might be considered as one of the most anticipated astrophysical events of the century. Following the collapse of the star's core, a dense proto-neutron star (PNS) forms. Within this PNS, complex dynamics involving convection instabilities,...
