Kavli Affiliate: Roger Blandford | First 5 Authors: Payel Mukhopadhyay, Enrico Peretti, Noemie Globus, Paul Simeon, Roger Blandford | Summary: The origin of cosmic rays above the knee in the spectrum is an unsolved problem. We present a wind model in which interstellar gas flows along a non-rotating, expanding flux tube with a changing speed […]
Philip F. Hopkins, Alexander B. Gurvich, Xuejian Shen, Zachary Hafen, Michael Y. Grudic | Summary: [[{“value”:”As they grow, galaxies can transition from irregular/spheroidal with ‘bursty’ star formation histories (SFHs), to disky with smooth SFHs. But even in simulations, the direct physical cause of such transitions remains unclear. We therefore explore this in a large suite […]
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 […]
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 […]

Kavli Affiliate: Yingjie Peng | First 5 Authors: Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández, Carles Badenes, Kat Barger | Summary: The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific programs, or "Mappers": Milky Way Mapper […]
Kavli Affiliate: J. Todd Hoeksema | First 5 Authors: Donald M. Hassler, Sarah E Gibson, Jeffrey S Newmark, Nicholas A. Featherstone, Lisa Upton | Summary: Solaris is a transformative Solar Polar Discovery-class mission concept to address crucial outstanding questions that can only be answered from a polar vantage. Solaris will image the Sun’s poles from […]
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 […]
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 […]
