Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Sven Herrmann, Peter Orel, Tanmoy Chattopadhyay, Glenn Morris, Gregory Prigozhin | Summary: Future strategic X-ray astronomy missions will require unprecedentedly sensitive wide-field imagers providing high frame rates, low readout noise and excellent soft energy response. To meet these needs, our team is employing a multi-pronged approach […]

Kavli Affiliate: Gregory Prigozhin | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, Kevan Donlon, Steven W. Allen | Summary: Single electron Sensitive Read Out (SiSeRO) is a novel on-chip charge detection technology that can, in principle, provide significantly greater responsivity and improved noise performance than traditional charge coupled device (CCD) readout circuitry. The […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Alvaro Pozo, Tom Broadhurst, Razieh Emami, Philip Mocz, Mark Vogelsberger | Summary: We compare the abundant prolate shaped galaxies reported beyond z$>$3 in deep JWST surveys, with the predicted {it stellar} appearance of young galaxies in detailed hydro-simulations of three main dark matter contenders: Cold (CDM), Wave/Fuzzy […]

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: José A. Benavides, Laura V. Sales, Mario. G. Abadi, Mark Vogelsberger, Federico Marinacci | Summary: We study the stellar properties of a sample of simulated ultra-diffuse galaxies (UDGs) with stellar mass $M_star=10^{7.5}$ – $10^{9} ~ rm{M_{odot}}$, selected from the TNG50 simulation, where UDGs form mainly in high-spin […]

Ofek | Summary: In the pursuit of understanding the population of stellar remnants within the Milky Way, we analyze the sample of $sim 950$ microlensing events observed by the Spitzer Space Telescope between […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Chien-Ting J. Chen, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim, Laura Di Gesu | Summary: We present multiwavelength polarization measurements of the luminous blazar Mrk~501 over a 14-month period. The 2–8 keV X-ray polarization was measured with the Imaging X-ray Polarimetry Explorer (IXPE) with six 100-ks […]
