Kavli Affiliate: Herman L. Marshall | First 5 Authors: Steven R. Ehlert, Riccardo Ferrazzoli, Andrea Marinucci, Herman L. Marshall, Riccardo Middei | Summary: We present measurements of the polarization of X-rays in the $2-8 thinspace mathrm{keV}$ band from the nucleus of the radio galaxy Centaurus A (Cen A), using a 100ks observation from the Imaging […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Niccolò Bucciantini, Riccardo Ferrazzoli, Matteo Bachetti, John Rankin, Niccolò Di Lalla | Summary: The Crab pulsar and its nebula are among the most studied astrophysical systems, and constitute one of the most promising environments where high energy processes and particle acceleration can be investigated. They are […]
Kavli Affiliate: Erin Kara | First 5 Authors: Christos Panagiotou, Iossif Papadakis, Erin Kara, Elias Kammoun, Michal Dovčiak | Summary: The UV/optical variability of AGN has long been thought to be driven by the X-ray illumination of the accretion disk. However, recent multi-wavelength campaigns of nearby Seyfert galaxies seem to challenge this paradigm, with an […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Alexander P. Ji, Joshua D. Simon, Ian U. Roederer, Ekaterina Magg, Anna Frebel | Summary: The ultra-faint dwarf galaxy Reticulum~II was enriched by a single rare and prolific r-process event. The r-process content of Reticulum~II thus provides a unique opportunity to study metal mixing in a relic […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Jubee Sohn, Margaret J. Geller, Mark Vogelsberger, Josh Borrow, | Summary: We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at $z < 2$ based on the IllustrisTNG-300 simulation. We select 270 massive clusters with $M_{200} < 10^{14}~{rm […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Sylvia Biscoveanu, Philippe Landry, Salvatore Vitale, , | Summary: Neutron star-black hole (NSBH) mergers detected in gravitational-waves have the potential to shed light on supernova physics, the dense matter equation of state, and the astrophysical processes that power their potential electromagnetic counterparts. We use the population of […]
Kavli Affiliate: Eric Miller | First 5 Authors: Renato A. Dupke, Yolanda Jimenez-teja, Yuanyuan Su, Eleazar R. Carrasco, Anton M. Koekemoer | Summary: Fossil groups (FG) of galaxies still present a puzzle to theories of structure formation. Despite the low number of bright galaxies, they have relatively high velocity dispersions and ICM temperatures often corresponding […]
Kavli Affiliate: Melania Nynka | First 5 Authors: Samar Safi-Harb, Brydyn Mac Intyre, Shuo Zhang, Isaac Pope, Shuhan Zhang | Summary: We present a broadband X-ray study of W50 (`the Manatee nebula’), the complex region powered by the microquasar SS 433, that provides a test-bed for several important astrophysical processes. The W50 nebula, a Galactic […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J Fernando Barbero G, Marc Basquens, Bogar Díaz, Eduardo J S Villaseñor, | Summary: The purpose of this paper is to discuss a number of issues that crop up in the computation of Poisson brackets in field theories. This is specially important for the canonical approaches […]
