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: Eric D. Miller | 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 […]

Polarized Image of a Synchrotron-emitting Ring in Einstein-Maxwell-scalar Theory

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Yiqian Chen, Lang Cheng, Peng Wang, Haitang Yang, | Summary: This study investigates polarized images of an equatorial synchrotron-emitting ring surrounding hairy black holes within the Einstein-Maxwell-scalar theory. Our analysis demonstrates qualitative similarities between the polarization patterns of hairy black holes and Schwarzschild black holes. However, due […]

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 […]

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 […]
