The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole
Dheeraj R. Pasham, Matteo Lucchini, Tanmoy Laskar +63
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boos…
Revealing the progenitor of SN 2021zby through analysis of the shock-cooling light curve
Qinan Wang, Patrick Armstrong, Yossef Zenati +34
We present early observations and analysis of the double-peaked Type IIb supernova (SN IIb) 2021zby. captured the prominent early shock cooling peak of SN 2021zby within the…
Exploring stellar and ionized gas non--circular motions in barred galaxies with MUSE
Carlos Lopez-Coba, Sebastian F. Sanchez, Lihwai Lin +5
We present MUSE integral field stellar and ionized velocity maps for a sample of 14 barred galaxies. Most of these objects exhibit "S"-shape iso-velocities in the bar region indica…
Examining the Properties of Low-Luminosity Hosts of Type Ia Supernovae from ASAS-SN
Thomas W. -S. Holoien, Vera L. Berger, Jason T. Hinkle +14
We present a spectroscopic analysis of 44 low-luminosity host galaxies of Type Ia supernovae (SNe Ia) detected by the All-Sky Automated Survey for Supernovae (ASAS-SN), using the e…
Spatial metallicity distribution statistics at pc scales in the AMUSING++ nearby galaxy sample
Zefeng Li, Emily Wisnioski, J. Trevor Mendel +6
We analyse the spatial statistics of the 2D gas-phase oxygen abundance distributions in a sample of 219 local galaxies. We introduce a new adaptive binning technique to enhance the…
Two years of optical and NIR observations of the superluminous supernova UID 30901 discovered by the UltraVISTA SN survey
Emilio D. Hueichapán, Carlos Contreras V., Regis Cartier +6
We present deep optical and near-infrared photometry of UID 30901, a superluminous supernova (SLSN) discovered during the UltraVISTA survey. The observations were obtained with VIR…
Weak Mass Loss from the Red Supergiant Progenitor of the Type II SN 2021yja
Griffin Hosseinzadeh, Charles D. Kilpatrick, Yize Dong +56
We present high-cadence optical, ultraviolet (UV), and near-infrared data of the nearby ( Mpc) Type II supernova (SN) 2021yja. Many Type II SNe show signs of interactio…
Systematic errors on optical-SED stellar mass estimates for galaxies across cosmic time and their impact on cosmology
A. Paulino-Afonso, S. González-Gaitán, L. Galbany +7
Studying galaxies at different cosmic epochs entails several observational effects that need to be taken into account to compare populations across a large time span in a consisten…
