Breaking Bad Degeneracies with Love: Improving gravitational-wave measurements through universal relations

Posted by klaurent October 17, 2022November 1, 2022Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Yiqi Xie, Deep Chatterjee, Gilbert Holder, Daniel E. Holz, Scott Perkins | Summary: The distance-inclination degeneracy limits gravitational-wave parameter estimation of compact binary mergers. Although the degeneracy can be partially broken by including higher-order modes or precession, these effects are suppressed in binary neutron stars. In […]

Dark Matter Induced Power in Quantum Devices

Posted by klaurent October 17, 2022Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: We present single quasiparticle devices as new dark matter (DM) detectors. The threshold of these devices is set by the cooper pair binding energy, and is therefore so low that they can detect DM as light as […]

Dark Matter Induced Power in Quantum Devices

Posted by dbos October 17, 2022Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Anirban Das, Noah Kurinsky, Rebecca K. Leane, , | Summary: We point out that power measurements of single quasiparticle devices open a new avenue to detect dark matter (DM). The threshold of these devices is set by the Cooper pair binding energy, and is therefore so low […]

Interpretations of the cosmic ray secondary-to-primary ratios measured by DAMPE

Posted by klaurent October 17, 2022November 1, 2022Stanford

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Peng-Xiong Ma, Zhi-Hui Xu, Qiang Yuan, Xiao-Jun Bi, Yi-Zhong Fan | Summary: Precise measurements of the boron-to-carbon and boron-to-oxygen ratios by DAMPE show clear hardenings around $100$ GeV/n, which provide important implications on the production, propagation, and interaction of Galactic cosmic rays. In this work we […]

Two Modes of LyC Escape From Bursty Star Formation: Implications for [C II] Deficits and the Sources of Reionization

Posted by dbos October 17, 2022Cambridge

Kavli Affiliate: Martin Haehnelt | First 5 Authors: Harley Katz, Aayush Saxena, Joki Rosdahl, Taysun Kimm, Jeremy Blaizot | Summary: We use the SPHINX$^{20}$ cosmological radiation hydrodynamics simulation to study how Lyman Continuum (LyC) photons escape from galaxies and the observational signatures of this escape. We define two classes of LyC leaker: Bursty Leakers and […]

A new alloy for Al-chalcogen system: AlSe surface alloy on Al (111)

Posted by klaurent October 17, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: En-Ze Shao, Kai Liu, Hao Xie, Kaiqi Geng, Keke Bai | Summary: Metal chalcogenide is a promising material for studying novel underlying physical phenomena and nanoelectronics applications. Here, we systematically investigate the crystal structure and electronic properties of the AlSe surface alloy on Al (111) using scanning […]

CO($J$=1-0) mapping survey of 64 galaxies in the Fornax cluster with the ALMA Morita array

Posted by klaurent October 17, 2022November 1, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Kana Morokuma-Matsui, Kenji Bekki, Jing Wang, Paolo Serra, Yusei Koyama | Summary: We conduct a $^{12}$C$^{16}$O($J$=1-0) (hereafter CO) mapping survey of 64 galaxies in the Fornax cluster using the ALMA Morita array in cycle 5. CO emission is detected from 23 out of the 64 galaxies. Our […]
