A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
Hard X-ray Observations of the Hydrogen-poor Superluminous Supernova SN 2018hti with NuSTAR
Igor Andreoni, Wenbin Lu, Brian Grefenstette +3
Some Hydrogen-poor superluminous supernovae are likely powered by a magnetar central engine, making their luminosity larger than common supernovae. Although a significant amount of…
Volumetric rates of Luminous Red Novae and Intermediate Luminosity Red Transients with the Zwicky Transient Facility
Viraj R. Karambelkar, Mansi M. Kasliwal, Nadejda Blagorodnova +27
Luminous red novae (LRNe) are transients characterized by low luminosities and expansion velocities, and are associated with mergers or common envelope ejections in stellar binarie…
Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky
Ariel Goobar, Joel Johansson, Steve Schulze +35
Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a s…
A radio-detected Type Ia supernova with helium-rich circumstellar material
Erik C. Kool, Joel Johansson, Jesper Sollerman +34
Type Ia supernovae (SNe Ia) are thermonuclear explosions of degenerate white dwarf (WD) stars destabilized by mass accretion from a companion star, but the nature of their progenit…
Probing the low-mass end of core-collapse supernovae using a sample of strongly-stripped Calcium-rich Type IIb Supernovae from the Zwicky Transient Facility
Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +23
The fate of stars in the zero-age main-sequence (ZAMS) range Msun is unclear. They could evolve to form white dwarfs or explode as electron-capture supernovae (SNe)…
