Characterization of a set of small planets with TESS and CHEOPS and an analysis of photometric performance

Posted by klaurent January 19, 2023MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Dominic Oddo, Diana Dragomir, Alexis Brandeker, Hugh P. Osborn, Karen Collins | Summary: The radius valley carries implications for how the atmospheres of small planets form and evolve, but this feature is visible only with highly precise characterizations of many small planets. We present the characterization of […]

Probing the interplay between jets, winds and multi-phase gas in 11 radio-quiet PG Quasars: A uGMRT-VLA study

Posted by klaurent January 19, 2023Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Silpa S., P. Kharb, Luis C. Ho, C. M. Harrison, | Summary: We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index and polarization properties from the VLA […]

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

Posted by klaurent January 18, 2023MIT

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

Posted by January 17, 2023Chicago

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

Posted by dbos January 9, 2023Tokyo

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 […]
