Prospects for constraining quasar ages with fiber spectrographs: Quasar-induced Ly$α$ emission from the intergalactic medium

Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryuichiro Hada, Masahiro Takada, Akio K. Inoue, , | Summary: We present a theoretical framework for linking quasar properties, such as quasar age, to the surrounding Ly$alpha$ emission intensity. In particular, we focus on a method for mapping the large-scale structure of Ly$alpha$ emission intensity with galaxy […]

L-function genera and applications

Kavli Affiliate: Andrei Okounkov | First 5 Authors: David Kazhdan, Andrei Okounkov, , , | Summary: We introduce equivariant L-genera associated to actions of Galois and related groups on algebraic varieties. We explain the role which these L-genera play in the spectral analysis of Eisenstein series. We also discuss the natural categorification of L-genera and […]

Constraints on the origin of the radio synchrotron background via angular correlations

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Elisa Todarello, Marco Regis, Federico Bianchini, Jack Singal, Enzo Branchini | Summary: The origin of the radio synchrotron background (RSB) is currently unknown. Its understanding might have profound implications in fundamental physics or might reveal a new class of radio emitters. In this work, we consider the […]

The Milky Way Tomography with Subaru Hyper Suprime-Cam. I. Halo substructures

Kavli Affiliate: Masahiro Takada | First 5 Authors: Yoshihisa Suzuki, Masashi Chiba, Yutaka Komiyama, Kohei Hayashi, Masayuki Tanaka | Summary: We analyze the photometric data in the Wide layer of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) over $sim 1,200$ deg$^{2}$ to uncover new halo substructures beyond the distance, $D_{odot}sim$ 30 kpc, from the Sun. […]

A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios

Kavli Affiliate: T. Higuchi | First 5 Authors: M. J. Borchert, J. A. Devlin, S. E. Erlewein, M. Fleck, J. A. Harrington | Summary: The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter in the observable universe […]

JWST and ALMA discern the assembly of structural and obscured components in a high-redshift starburst galaxy

Kavli Affiliate: John D. Silverman | First 5 Authors: Zhaoxuan Liu, John D. Silverman, Emanuele Daddi, Annagrazia Puglisi, Alvio Renzini | Summary: We present observations and analysis of the starburst, PACS-819, at z=1.45 ($M_*=10^{10.7}$ M$_{ odot}$), using high-resolution ($0^{prime prime}.1$; 0.8 kpc) ALMA and multi-wavelength JWST images from the COSMOS-Web program. Dissimilar to HST/ACS images […]
