From X-rays to physical parameters: a comprehensive analysis of thermal tidal disruption event X-ray spectra

Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Andrew Mummery, Thomas Wevers, Richard Saxton, Dheeraj Pasham, | Summary: We perform a comprehensive analysis of a population of 19 X-ray bright tidal disruption events (TDEs), fitting their X-ray spectra with a new, physically self consistent, relativistic accretion disc model. Not all of the TDEs inhabit regions […]

White dwarf — red giant star binaries as Type Ia supernova progenitors: with and without magnetic confinement

Kavli Affiliate: Saul A. Rappaport | First 5 Authors: Iminhaji Ablimit, Philipp Podsiadlowski, Rosanne Di Stefano, Saul A. Rappaport, James Wicker | Summary: Various white-dwarf (WD) binary scenarios have been proposed trying to understand the nature and the diversity of Type Ia supernovae (SNe Ia). In this work, we study the evolution of carbon-oxygen WD […]

Unification of thermal and quantum noise in gravitational-wave detectors

Kavli Affiliate: Lee McCuller | First 5 Authors: Chris Whittle, Lee McCuller, Vivishek Sudhir, Matthew Evans, | Summary: Contemporary gravitational-wave detectors are fundamentally limited by thermal noise — due to dissipation in the mechanical elements of the test mass — and quantum noise — from the vacuum fluctuations of the optical field used to probe […]

The radio detection and accretion properties of the peculiar nuclear transient AT 2019avd

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yanan Wang, Ranieri D. Baldi, Santiago del Palacio, Muryel Guolo, Xiaolong Yang | Summary: AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and the infrared […]

A Multiwavelength study of the ongoing Changing-look AGN AT2021fxu

Kavli Affiliate: Dheeraj Pasham | First 5 Authors: Yukta Ajay, Muryel Guolo, Dheeraj Pasham, , | Summary: We present multiwavelength analyses of an active optical transient AT2021fxu which shows the appearance of previously absent broad emission lines in a recent optical spectrum, suggesting a Changing-look (CL) Active Galactic Nucleus (AGN). During the spectral transition, the […]

THESAN-HR: How does reionization impact early galaxy evolution?

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Josh Borrow, Rahul Kannan, Enrico Garaldi, Aaron Smith, Mark Vogelsberger | Summary: Early galaxies were the radiation source for reionization, with the photoheating feedback from the reionization process expected to reduce the efficiency of star formation in low mass haloes. Hence, to fully understand reionization and galaxy […]
