Late-time Hubble Space Telescope Ultraviolet Spectra of SN 2023ixf and SN 2024ggi Show Ongoing Interaction with Circumstellar Material
K. Azalee Bostroem, Stefano Valenti, David J. Sand +31
We present far- and near-ultraviolet (UV) spectra of the Type II supernovae (SNe) SN~2023ixf from days 199 to 722 and SN~2024ggi at days 41 and 232. Both supernovae show broad, blu…
Milli-to-Deci-Hertz Detection Prospects for Gravitational Waves from Core-Collapse Supernovae
Kiranjyot Gill
Gravitational wave (GW) astronomy truly began with the detection of merging compact binaries. The next breakthrough lies in detecting GWs from core-collapse supernovae (CCSNe), par…
Roman CCS White Paper: Characterizing Superluminous Supernovae with Roman
Sebastian Gomez, Kate Alexander, Edo Berger +16
Type-I Superluminous Supernovae (SLSNe) are an exotic class of core-collapse SN (CCSN) that can be up to 100 times brighter and more slowly-evolving than normal CCSNe. SLSNe repres…
Constraining the Time of Gravitational Wave Emission from Core-Collapse Supernovae
Kiranjyot Gill, Griffin Hosseinzadeh, Edo Berger +2
The advent of sensitive gravitational wave (GW) detectors, coupled with wide-field, high cadence optical time-domain surveys, raises the possibility of the first joint GW-electroma…
Modeling Core-Collapse Supernovae Gravitational-Wave Memory in Laser Interferometric Data
Colter Richardson, Michele Zanolin, Haakon Andresen +3
We study the properties of the gravitational wave (GW) emission between Hz and Hz (which we refer to as low-frequency emission) from core-collapse supernovae, in the…
Gravitational waves from three-dimensional core-collapse supernova models: The impact of moderate progenitor rotation
H. Andresen, E. Müller, H. -Th. Janka +3
We present predictions for the gravitational-wave (GW) emission of three-dimensional supernova (SN) simulations performed for a 15 solar-mass progenitor with the Prometheus-Vertex…
Enhancing the Sensitivity of Searches for Gravitational Waves from Core-Collapse Supernovae with a Bayesian classification of candidate events
Kiranjyot Gill, Wenhui Wang, Oscar Valdez +3
We demonstrate how a morphological veto involving Bayesian statistics can improve the receiver-operating characteristic (ROC) curves of the current search for core-collapse superno…
