Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Roberto Maiolino, Asa F. L. Bluck, Francesco Belfiore, Mirko Curti | Summary: One of the most important questions in astrophysics is what causes galaxies to stop forming stars. Previous studies have shown a tight link between quiescence and black hole mass. Other studies have […]
Kavli Affiliate: Jia Liu | First 5 Authors: Mingxuan Du, Jia Liu, Xiao-Ping Wang, Tianhao Wu, | Summary: We investigate the enhancement of dark sector particle production within the scattering dominant regime. These particles typically exhibit a slight mixing with Standard Model particles through various portals, allowing for their generation through in-medium oscillation from Standard […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ailing Wang, Tao An, Yingkang Zhang, Xiaopeng Cheng, Luis C. Ho | Summary: This study uses multi-frequency Very Long Baseline Interferometry (VLBI) to study the radio emission from 10 radio-quiet quasars (RQQs) and four radio-loud quasars (RLQs). The diverse morphologies, radio spectra, and brightness temperatures observed […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Yifan Zhou, Brendan P. Bowler, Haifeng Yang, Aniket Sanghi, Gregory J. Herczeg | Summary: The proposed protoplanet AB Aur b is a spatially concentrated emission source imaged in the mm-wavelength disk gap of the Herbig Ae/Be star AB Aur. Its near-infrared spectrum and absence of strong […]
Kavli Affiliate: Chihway Chang | First 5 Authors: Meng-Xiang Lin, Bhuvnesh Jain, Marco Raveri, Eric J. Baxter, Chihway Chang | Summary: The $S_8$ tension between low-redshift galaxy surveys and the primary CMB signals a possible breakdown of the $Lambda$CDM model. Recently differing results have been obtained using low-redshift galaxy surveys and the higher redshifts probed […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: , , , , | Summary: In this paper we investigate the role of AGN feedback on the late stage evolution of elliptical galaxies by performing high-resolution hydrodynamical simulation in the {it MACER} framework. By comparing models that take into account different feedback mechanisms, namely AGN and […]
Kavli Affiliate: Angela V. Olinto | First 5 Authors: Johannes Eser, Angela V. Olinto, Lawrence Wiencke, , | Summary: Observing ultra-high energy cosmic rays (UHECR) and very high energy (VHE) neutrinos from space is a promising way to measure their extremely low fluxes by significantly increasing the observed volume. The Extreme Universe Space Observatory on […]
