Optical Appearance of Eccentric Tidal Disruption Events

Fangyi, Hu, Daniel J. Price +1

Stars approaching supermassive black holes can be tidally disrupted. Despite being expected to emit X-rays, TDEs have been largely observed in optical bands, which is poorly unders…

An upper limit on the spins of merging binary black holes formed through binary evolution

Pablo Marchant, Philipp Podsiadlowski, Ilya Mandel

As gravitational wave detectors improve, observations of black hole (BH) mergers will provide the joint distribution of their masses and spins. This will be a critical benchmark to…

Which black hole is spinning? Probing the origin of black-hole spin with gravitational waves

Christian Adamcewicz, Shanika Galaudage, Paul D. Lasky +1

Theoretical studies of angular momentum transport suggest that isolated stellar-mass black holes are born with negligible dimensionless spin magnitudes . However, r…

GW190521: tracing imprints of spin-precession on the most massive black hole binary

Simona J. Miller, Maximiliano Isi, Katerina Chatziioannou +2

GW190521 is a remarkable gravitational-wave signal on multiple fronts: its source is the most massive black hole binary identified to date and could have spins misaligned with its…

Fallback onto Kicked Neutron Stars and its Effect on Spin-Kick Alignment

B. Müller

Fallback in core-collapse supernova explosions is potentially of significant importance for the birth spins of neutron stars and black holes. It has recently been pointed out that…

The carbon-rich type Ic supernova 2016adj in the iconic dust lane of Centaurus A: signatures of interaction with circumstellar hydrogen?

Maximilian D. Stritzinger, Eddie Baron, Francesco Taddia +24

We present a comprehensive data set of supernova (SN) 2016adj located within the central dust lane of Centaurus A. SN 2016adj is significantly reddened and after correcting the pea…
