Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: In the past few years, many mesoscale systems have been proposed as possible detectors of sub-GeV dark matter particles. In this work, we point out the feasibility of probing dark matter-nucleon scattering cross section using superconductor-based quantum […]
Kavli Affiliate: Michael Miller | Authors: Sonya Kumar Bharathkar, Michael J. Miller and Beth M. Stadtmueller | Summary: Secretory (S) Immunoglobin (Ig) A is the predominant mucosal antibody, which mediates host interactions with commensal and pathogenic microbes, including Clostridioides difficile. SIgA adopts a polymeric IgA structure that is bound by secretory component (SC). Despite significance, […]
Kavli Affiliate: Peter Graham | First 5 Authors: Thomas G. White, Hannah Poole, Emma E. McBride, Matthew Oliver, Adrien Descamps | Summary: We present direct observations of acoustic waves in warm dense matter. We analyze wave-number- and energy-resolved x-ray spectra taken from warm dense methane created by laser heating a cryogenic liquid jet. X-ray diffraction […]

Kavli Affiliate: David A. Principe | First 5 Authors: Lia Corrales, Keivan G. Stassun, Tim Cunningham, Girish Duvvuri, Jeremy J. Drake | Summary: One of the key research themes identified by the Astro2020 decadal survey is Worlds and Suns in Context. The Advanced X-ray Imaging Satellite (AXIS) is a proposed NASA APEX mission that will […]
Kavli Affiliate: Erin Kara | First 5 Authors: The AXIS Time-Domain, Multi-Messenger Science Working Group, :, Riccardo Arcodia, Franz E. Bauer | Summary: The Advanced X-ray Imaging Satellite (AXIS) promises revolutionary science in the X-ray and multi-messenger time domain. AXIS will leverage excellent spatial resolution (<1.5 arcsec), sensitivity (80x that of Swift), and a large […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Peter W. Graham, Harikrishnan Ramani, , , | Summary: We place limits on dark matter made up of compact objects significantly heavier than a solar mass, such as MACHOs or primordial black holes (PBHs). In galaxies, the gas of such objects is generally hotter than the […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Tao Wang, Ke Xu, Yuxuan Wu, Yong Shi, David Elbaz | Summary: Nearly every massive galaxy contains a supermassive black hole (BH) at its center. For decades, both theory and numerical simulations have indicated that BHs play a central role in regulating the growth and quenching […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: Zachary Bogorad, Peter W. Graham, Harikrishnan Ramani, , | Summary: Many models of dark matter include self-interactions beyond gravity. A variety of astrophysical observations have previously been used to place limits on the strength of such self-interactions. However, previous works have generally focused either on short-range […]
