X-ray spectral performance of the Sony IMX290 CMOS sensor near Fano limit after a per-pixel gain calibration

Posted by dbos MIT

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Benjamin Schneider, Gregory Prigozhin, Richard F. Foster, Marshall W. Bautz, Hope Fu | Summary: The advent of back-illuminated complementary metal-oxide-semiconductor (CMOS) sensors and their well-known advantages over charge-coupled devices (CCDs) make them an attractive technology for future X-ray missions. However, numerous challenges remain, including improving their […]

Hitting the mark: Optimising Marked Power Spectra for Cosmology

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jessica A. Cowell, David Alonso, Jia Liu, , | Summary: Marked power spectra provide a computationally efficient way to extract non-Gaussian information from the matter density field using the usual analysis tools developed for the power spectrum without the need for explicit calculation of higher-order correlators. In […]

Two Channels of Metal-Rich Compact Stellar System Formation: Starbursts Under High Ram Pressure vs. Tidal Stripping

Posted by dbos Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yuan Bian, Min Du, Victor P. Debattista, Dylan Nelson, Mark A. Norris | Summary: Most galaxies follow well-defined scaling relations of metallicity and stellar mass; however, some outliers at the low mass end of the observed galaxy population exhibit unusually high metallicity for their mass. Understanding […]

A novel standard candle: collapsing axion stars

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Haoran Di, Lijing Shao, Zhu Yi, Shi-Bei Kong, | Summary: The Hubble constant, $H_0$, is a crucial parameter in cosmology. However, various cosmic observations have produced differing posterior values for $H_0$, resulting in what is referred to as the $H_0$ tension. To resolve this discrepancy, utilizing other […]

Neutron stars in the bumblebee theory of gravity

Posted by dbos Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Peixiang Ji, Zhuhai Li, Lirui Yang, Rui Xu, Zexin Hu | Summary: Recently, theoretical studies on the bumblebee gravity model, a nonminimally-coupled vector-tensor theory that violates the Lorentz symmetry, have flourished, with a simultaneous increase in the utilization of observations to impose constraints. The static spherical solutions […]
