Stringent $σ_8$ constraints from small-scale galaxy clustering using a hybrid MCMC+emulator framework

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Sihan Yuan, Lehman H. Garrison, Daniel J. Eisenstein, Risa H. Wechsler, | Summary: We present a novel simulation-based hybrid emulator approach that maximally derives cosmological and Halo Occupation Distribution (HOD) information from non-linear galaxy clustering, with sufficient precision for DESI Year 1 (Y1) analysis. Our hybrid […]

Being KLEVER at cosmic noon: ionised gas outflows are inconspicuous in low-mass star-forming galaxies but prominent in massive AGN hosts

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Alice Concas, Roberto Maiolino, Mirko Curti, Connor Hayden-Pawson, Michele Cirasuolo | Summary: We investigate the presence of ionised gas outflows in a sample of 141 main-sequence star-forming galaxies at $1.2<z<2.6$ from the KLEVER (KMOS Lensed Emission Lines and VElocity Review) survey. Our sample covers an exceptionally wide […]

COOL-LAMPS II. Characterizing the Size and Star Formation History of a Bright Strongly Lensed Early-Type Galaxy at Redshift 1.02

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Ezra Sukay, Gourav Khullar, Michael D. Gladders, Keren Sharon, Guillaume Mahler | Summary: We present COOL J1323+0343, an early-type galaxy at $z = 1.0153 pm 0.0006$, strongly lensed by a cluster of galaxies at z = $z = 0.353 pm 0.001$. This object was originally imaged […]

CP2: Copy-Paste Contrastive Pretraining for Semantic Segmentation

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Huiyu Wang, Chen Wei, Alan Yuille, Wei Shen | Summary: Recent advances in self-supervised contrastive learning yield good image-level representation, which favors classification tasks but usually neglects pixel-level detailed information, leading to unsatisfactory transfer performance to dense prediction tasks such as semantic segmentation. In this […]

Informal Socialization in Physics Training

Kavli Affiliate: Brian D. Nord | First 5 Authors: Apriel K Hodari, Shayna B Krammes, Chanda Prescod-Weinstein, Brian D Nord, Jessica N Esquivel | Summary: This paper addresses issues related to the process of informal socialization into physics, particularly for senior graduate students and postdoctoral scholars. Many physicists’ careers are built on the relationships they […]

Widely-tunable optical parametric oscillator in lithium niobate nanophotonics

Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Ledezma, Arkadev Roy, Luis Costa, Ryoto Sekine, Robert Gray | Summary: Widely-tunable coherent sources in nanophotonics are desirable for a multitude of applications ranging from communications to sensing. The mid-infrared spectral region (wavelengths beyond 2 $mu$m) is particularly important because of applications related to molecular spectroscopy. […]
