Kavli Affiliate: Michael McDonald | First 5 Authors: Francesco Ubertosi, Myriam Gitti, Fabrizio Brighenti, Gianfranco Brunetti, Michael McDonald | Summary: We present the first results of a deep $Chandra$ observation of the galaxy cluster RBS 797, whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-W) direction. Follow-up VLA radio observations of […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Logan A. Pearce, Andrew Vanderburg, , | Summary: The long-period giant planet HR 5183 b has one of the most extreme orbits among exoplanets known to date. In this work we use Hipparcos-Gaia astrometry to measure the orbital inclination of this planet for the first […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: We report on the population properties of 76 compact binary mergers detected with gravitational waves below a false alarm rate of 1 per year through GWTC-3. The catalog contains three […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Maya Fishbach, Reed Essick, Daniel E. Holz, Shanika Galaudage | Summary: We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars and black holes. We analyze all gravitational wave detections by LIGO-Virgo made […]
Kavli Affiliate: Thomas M. Crawford | First 5 Authors: Michael Janssen, Heino Falcke, Matthias Kadler, Eduardo Ros, Maciek Wielgus | Summary: Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of extragalactic radio jets, down to $10-100$ gravitational radii ($r_g=GM/c^2$) scales in […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Hengxiao Guo, Aaron J. Barth, Kirk T. Korista, Michael R. Goad, Edward M. Cackett | Summary: Photoionization modeling of active galactic nuclei (AGN) predicts that diffuse continuum (DC) emission from the broad-line region makes a substantial contribution to the total continuum emission from ultraviolet through near-infrared […]
Kavli Affiliate: Lina Necib | First 5 Authors: Daniel McKeown, James S. Bullock, Francisco J. Mercado, Zachary Hafen, Michael Boylan-Kolchin | Summary: We use FIRE-2 zoom cosmological simulations of Milky Way size galaxy halos to calculate astrophysical J-factors for dark matter annihilation and indirect detection studies. In addition to velocity-independent (s-wave) annihilation cross sections $sigma_v$, […]
Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Yong Chen, Mumien Cheng, Chen Jia, | Summary: The $L^p$ maximal inequalities for martingales are one of the classical results in the theory of stochastic processes. Here we establish the sharp moderate maximal inequalities for one-dimensional diffusion processes, which include the $L^p$ maximal inequalities as […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Anne Noer Kolborg, Davide Martizzi, Enrico Ramirez-Ruiz, Hugo Pfister, Charli Sakari | Summary: The extent to which turbulence mixes gas in the face of recurrent infusions of fresh metals by supernovae (SNe) could help provide important constraints on the local star formation conditions. This includes predictions […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Chantanelle Nava, Mercedes López-Morales, Annelies Mortier, Li Zeng, Helen A. C. Giles | Summary: We present mass and radius measurements of K2-79b and K2-222b, two transiting exoplanets orbiting active G-type stars. Their respective 10.99d and 15.39d orbital periods fall near periods of signals induced by stellar magnetic […]
