From haloes to galaxies. III. The gas cycle of local galaxy populations

Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: In Dou et al. (2021), we introduced the Fundamental Formation Relation (FFR), a tight relation between specific SFR (sSFR), H$_2$ star formation efficiency (SFE$_{rm H_2}$), and the ratio of H$_2$ to stellar mass. Here […]

Via Machinae: Searching for Stellar Streams using Unsupervised Machine Learning

Kavli Affiliate: Lina Necib | First 5 Authors: David Shih, Matthew R. Buckley, Lina Necib, John Tamanas, | Summary: We develop a new machine learning algorithm, Via Machinae, to identify cold stellar streams in data from the Gaia telescope. Via Machinae is based on ANODE, a general method that uses conditional density estimation and sideband […]

High redshift JWST predictions from IllustrisTNG: III. Infrared luminosity functions, obscured star formation and dust temperature of high-redshift galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Dylan Nelson, Sandro Tacchella, Lars Hernquist | Summary: We post-process galaxies in the IllustrisTNG simulations with SKIRT radiative transfer calculations to make predictions for the rest-frame near-infrared (NIR) and far-infrared (FIR) properties of galaxies at $zgeq 4$. The rest-frame $K$- and $z$-band galaxy […]

Search for $B^{+}to K^{+}νbarν$ decays using an inclusive tagging method at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, P. Ahlburg | Summary: A search for the flavor-changing neutral-current decay $B^{+}to K^{+}nubar{nu}$ is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The results are based on a data sample corresponding to an […]

Neutral vs Ion Linewidths in Barnard 5: Evidence for Penetration by MHD Waves

Kavli Affiliate: Sarah E. Church | First 5 Authors: Jaime E. Pineda, Anika Schmiedeke, Paola Caselli, Steven W. Stahler, David T. Frayer | Summary: Dense cores are the final place where turbulence is dissipated. It has been proposed from theoretical arguments that the non-thermal velocity dispersion should be narrower both for molecular ions (compared to […]

Effects of model incompleteness on the drift-scan calibration of radio telescopes

Kavli Affiliate: Max Tegmark | First 5 Authors: Bharat K. Gehlot, Daniel C. Jacobs, Judd D. Bowman, Nivedita Mahesh, Steven G. Murray | Summary: Precision calibration poses challenges to experiments probing the redshifted 21-cm signal of neutral hydrogen from the Cosmic Dawn and Epoch of Reionization (z~30-6). In both interferometric and global signal experiments, systematic […]

TOI-1431b/MASCARA-5b: A Highly Irradiated Ultra-Hot Jupiter Orbiting One of the Hottest & Brightest Known Exoplanet Host Stars

Kavli Affiliate: Alan M. Levine | First 5 Authors: Brett Christopher Addison, Emil Knudstrup, Ian Wong, Guillaume Hebrard, Patrick Dorval | Summary: We present the discovery of a highly irradiated and moderately inflated ultra-hot Jupiter, TOI-1431b/MASCARA-5b (HD 201033b), first detected by NASA’s Transiting Exoplanet Survey Satellite mission (TESS) and the Multi-site All-Sky CAmeRA (MASCARA). The […]

X-ray polarimetry of the Crab nebula with PolarLight: polarization recovery after the glitch and a secular position angle variation

Kavli Affiliate: Renxin Xu | First 5 Authors: Xiangyun Long, Hua Feng, Hong Li, Jiahuan Zhu, Qiong Wu | Summary: We report follow-up observations of the Crab nebula with the PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated with a pulsar glitch in 2019. The new observations confirm that the polarization has […]

Hermeian haloes: Field haloes that interacted with both the Milky Way and M31

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Oliver Newton, Noam I. Libeskind, Alexander Knebe, Miguel A. Sánchez-Conde, Jenny G. Sorce | Summary: The Local Group is a unique environment in which to study the astrophysics of galaxy formation. The proximity of the Milky Way and M31 enhances the frequency of interactions of the low-mass […]

Chandra Observations of Excess Fe K$α$ Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?

Kavli Affiliate: Claudio Ricci | First 5 Authors: Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen, Claudio Ricci, Alberto Masini | Summary: In active galactic nuclei (AGN), fluorescent Fe K$alpha$ (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on the scale of a few parsecs (pc).
