The effects of turbulence on galactic nuclear gas rings

Kavli Affiliate: R. Morris | First 5 Authors: Jesus M. Salas, Smadar Naoz, Mark R. Morris, , | Summary: The gas dynamics in the inner few kiloparsecs of barred galaxies often results in configurations that give rise to nuclear gas rings. However, the generic dynamical description of the formation of galactic nuclear rings does not […]

Assessing Classifier Fairness with Collider Bias

Kavli Affiliate: Ke Wang | First 5 Authors: Zhenlong Xu, Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li | Summary: The increasing application of machine learning techniques in everyday decision-making processes has brought concerns about the fairness of algorithmic decision-making. This paper concerns the problem of collider bias which produces spurious associations in fairness assessment […]

The X-ray properties of Eta Carinae during its 2020 X-ray minimum

Kavli Affiliate: David A. Principe | First 5 Authors: Amit Kashi, David A. Principe, Noam Soker, Joel H. Kastner, | Summary: The massive binary system Eta Carinae is characterized by intense colliding winds that form shocks and emit X-rays. The system is highly eccentric ($esimeq0.9$), resulting in modulated X-ray emission during its 5.54 year orbit. […]

A Tale of Two Transition Disks: ALMA long-baseline observations of ISO-Oph 2 reveal two closely packed non-axisymmetric rings and a $sim$2 au cavity

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales, Sebastián Pérez, Alice Zurlo | Summary: ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M$_{dust}$ $sim$40 M$_{oplus}$) ring-like disk with a dust cavity $sim$50 au in radius and the secondary […]

Searching for New Interactions at Sub-micron Scale Using the Mossbauer Effect

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Giorgio Gratta, David E. Kaplan, Surjeet Rajendran, , | Summary: A new technique to search for new scalar and tensor interactions at the sub-micrometer scale is presented. The technique relies on small shifts of nuclear gamma lines produced by the coupling between matter and the nuclei in […]

From haloes to galaxies — II. The fundamental relations in star formation and quenching

Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Alvio Renzini, Luis C. Ho, Filippo Mannucci | Summary: Star formation and quenching are two of the most important processes in galaxy formation and evolution. We explore in the local Universe the interrelationships among key integrated galaxy properties, including stellar mass $M_*$, star […]

Bounds on velocity-dependent dark matter-proton scattering from Milky Way satellite abundance

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Karime Maamari, Vera Gluscevic, Kimberly K. Boddy, Ethan O. Nadler, Risa H. Wechsler | Summary: We use the latest measurements of the Milky Way satellite population from the Dark Energy Survey and Pan-STARRS1 to infer the most stringent astrophysical bound to date on velocity-dependent interactions between […]

The TeV Cosmic Ray Bump: a Message from Epsilon Indi or Epsilon Eridani Star?

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Mikhail A. Malkov, Igor V. Moskalenko, , , | Summary: A recently observed bump in the cosmic ray (CR) spectrum from 0.3–30 TV is likely caused by a stellar bow shock that reaccelerates emph{preexisting} CRs, which further propagate to the Sun along the magnetic field lines. […]

On the accuracy of the ALMA flux calibration in the time domain and across spectral windows

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Logan Francis, Doug Johnstone, Gregory Herczeg, Todd R. Hunter, Daniel Harsono | Summary: A diverse array of science goals require accurate flux calibration of observations with the Atacama Large Millimeter/Submillimeter array (ALMA), however, this goal remains challenging due to the stochastic time-variability of the “grid” quasars ALMA […]
