Search for Axion Dark Matter from 1.1 to 1.3 GHz with ADMX

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: ADMX Collaboration, G. Carosi, C. Cisneros, N. Du, S. Durham | Summary: Axion dark matter can satisfy the conditions needed to account for all of the dark matter and solve the strong CP problem. The Axion Dark Matter eXperiment (ADMX) is a direct dark matter search using […]

Rapid inference and comparison of gravitational-wave population models with neural variational posteriors

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Matthew Mould, Noah E. Wolfe, Salvatore Vitale, , | Summary: The LIGO-Virgo-KAGRA catalog has been analyzed with an abundance of different population models due to theoretical uncertainty in the formation of gravitational-wave sources. To expedite model exploration, we introduce an efficient and accurate variational Bayesian approach that […]

Probing the UV with IR Axion Dark Matter Experiments

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Jacob M. Leedom, Serah Moldovsky, Hitoshi Murayama, , | Summary: There is an ongoing and future experimental program searching for axions as both extensions of the Standard Model and as candidates for the observed dark matter. In this paper, we examine the feasibility of being able to […]

COSMOS-Web: Unraveling the Evolution of Galaxy Size and Related Properties at $2<z<10$

Kavli Affiliate: John D. Silverman | First 5 Authors: Lilan Yang, Jeyhan S. Kartaltepe, Maximilien Franco, Xuheng Ding, Mark J. Achenbach | Summary: We measure galaxy sizes from $2 < z < 10$ using COSMOS-Web, the largest-area JWST imaging survey to date, covering $sim$0.54 deg$^2$. We analyze the rest-frame optical (~5000A) size evolution and its […]

Discovery of extreme Quasi-Periodic Eruptions in a newly accreting massive black hole

Kavli Affiliate: Claudio Ricci | First 5 Authors: Lorena Hernández-García, Joheen Chakraborty, Paula Sánchez-Sáez, Claudio Ricci, Jorge Cuadra | Summary: Quasi-periodic eruptions (QPEs) are rapid, recurring X-ray bursts from supermassive black holes, believed to result from interactions between accretion disks and surrounding matter. The galaxy SDSS1335+0728, previously stable for two decades, exhibited an increase in […]

Rapidly varying ionization features in a Quasi-periodic Eruption: a homologous expansion model for the spectroscopic evolution

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Peter Kosec, Erin Kara, Giovanni Miniutti, Riccardo Arcodia | Summary: Quasi-Periodic Eruptions (QPEs) are recurring bursts of soft X-ray emission from supermassive black holes (SMBHs), which a growing class of models explains via extreme mass-ratio inspirals (EMRIs). QPEs exhibit blackbody-like emission with significant temperature evolution, […]
