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 […]

Mineral Detection of Neutrinos and Dark Matter. A Whitepaper

Kavli Affiliate: Juan I. Collar | First 5 Authors: Sebastian Baum, Patrick Stengel, Natsue Abe, Javier F. Acevedo, Gabriela R. Araujo | Summary: Minerals are solid state nuclear track detectors – nuclear recoils in a mineral leave latent damage to the crystal structure. Depending on the mineral and its temperature, the damage features are retained […]

Searching for Ultralight Dark Matter Conversion in Solar Corona using Low Frequency Array Data

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]

Joint analysis constraints on the physics of the first galaxies with low frequency radio astronomy data

Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: Observations of the first billion years of cosmic history are currently limited. We demonstrate, using a novel machine learning technique, the synergy between observations of the sky-averaged 21-cm signal from neutral […]

Joint analysis constraints on the physics of the first galaxies with low frequency radio astronomy data

Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: The first billion years of cosmic history remains largely unobserved. We demonstrate, using a novel machine learning technique, how combining upper limits on the spatial fluctuations in the 21-cm signal with […]

TDCOSMO. XIII. Improved Hubble constant measurement from lensing time delays using spatially resolved stellar kinematics of the lens galaxy

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen, Tommaso Treu, Michele Cappellari | Summary: Strong-lensing time delays enable measurement of the Hubble constant ($H_{0}$) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the […]

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 […]
