Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Abel L. Peirson, Michela Negro, Ioannis Liodakis, Riccardo Middei, Dawoon E. Kim | Summary: We report the first $> 99%$ confidence detection of X-ray polarization in BL Lacertae. During a recent X-ray/$gamma$-ray outburst, a 287 ksec observation (2022 November 27-30) was taken using the Imaging X-ray Polarimetry […]
Kavli Affiliate: Grzegorz Madejski | First 5 Authors: Laura Di Gesu, Herman L. Marshall, Steven R. Ehlert, Dawoon E. Kim, Immacolata Donnarumma | Summary: The magnetic field conditions in astrophysical relativistic jets can be probed by multiwavelength polarimetry, which has been recently extended to X-rays. For example, one can track how the magnetic field changes […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, Bruce Macintosh, Dimitri Mawet | Summary: While radial velocity surveys have demonstrated that the population of gas giants peaks around $3~text{au}$, the most recent high-contrast imaging surveys have only been sensitive to planets beyond $sim~10~text{au}$. Sensitivity at small angular separations […]
Kavli Affiliate: Dustin M. Schroeder | First 5 Authors: Andrew Romero-Wolf, Gregor Steinbruegge, Julie Castillo-Rogez, Corey J. Cochrane, Tom A. Nordheim | Summary: We present a feasibility study for passive sounding of Uranian icy moons using Uranian Kilometric Radio (UKR) emissions in the 100 – 900 kHz band. We provide a summary description of the […]
Kavli Affiliate: Robert Cameron | First 5 Authors: Robert Cameron, Manfred Schüssler, , , | Summary: Theoretical models for the solar dynamo range from simple low-dimensional “toy models” to complex 3D-MHD simulations. Here we mainly discuss appproaches that are motivated and guided by solar (and stellar) observations. We give a brief overview of the evolution […]
Kavli Affiliate: Peter Orel | First 5 Authors: Tanmoy Chattopadhyay, Sven Herrmann, Peter Orel, Kevan Donlon, Gregory Prigozhin | Summary: We demonstrate so-called repetitive non-destructive readout (RNDR) for the first time on a Single electron Sensitive Readout (SiSeRO) device. SiSeRO is a novel on-chip charge detector output stage for charge-coupled device (CCD) image sensors, developed […]

Kavli Affiliate: Roger Romani | First 5 Authors: Ajay Ratheesh, Michal Dovčiak, Henric Krawczynski, Jakub Podgorný, Lorenzo Marra | Summary: Large, energy-dependent X-ray polarisation is observed in 4U 1630-47, a black hole in an X-ray binary, in the high-soft emission state. In this state, X-ray emission is believed to be dominated by a thermal, geometrically […]
Kavli Affiliate: Eric Charles | First 5 Authors: Michela Negro, Milena Crnogorčević, Eric Burns, Eric Charles, Lea Marcotulli | Summary: With the coincident detections of electromagnetic radiation together with gravitational waves (GW170817) or neutrinos (TXS 0506+056), the new era of multimessenger astrophysics has begun. Of particular interest are the searches for correlation between the high-energy […]
Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Alvaro Zamora, Tom Abel, , | Summary: Beyond standard summary statistics are necessary to summarize the rich information on non-linear scales in the era of precision galaxy clustering measurements. For the first time, we introduce the 2D k-th nearest neighbor (kNN) statistics as a summary […]
