Kavli Affiliate: Erin Kara | First 5 Authors: Constanza Echiburú-Trujillo, Alexandra J. Tetarenko, Daryl Haggard, Thomas D. Russell, Karri I. I. Koljonen | Summary: Black hole X-ray binaries (BH XRBs) are ideal targets to study the connection between accretion inflow and jet outflow. Here we present quasi-simultaneous, multi-wavelength observations of the Galactic black hole system […]

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Zhilei Xu, Honggeun Kim, Jacqueline N. Hewitt, Kai-Feng Chen, Nicholas S. Kern | Summary: The key to detecting neutral hydrogen during the epoch of reionization (EoR) is to separate the cosmological signal from the dominating foreground radiation. We developed direct optimal mapping (Xu et al. 2022) […]

Kavli Affiliate: George R. Ricker | First 5 Authors: Christopher R. Mann, Paul A. Dalba, David Lafrenière, Benjamin J. Fulton, Guillaume Hébrard | Summary: Large-scale exoplanet surveys like the TESS mission are powerful tools for discovering large numbers of exoplanet candidates. Single-transit events are commonplace within the resulting candidate list due to the unavoidable limitation […]

Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Geoffrey Mo, Rahul Jayaraman, Danielle Frostig, Michael M. Fausnaugh, Erik Katsavounidis | Summary: The observation of GW170817, the first binary neutron star merger observed in both gravitational waves (GW) and electromagnetic (EM) waves, kickstarted the age of multi-messenger GW astronomy. This new technique presents an observationally […]

Kavli Affiliate: David A. Principe | First 5 Authors: Lia Corrales, Keivan G. Stassun, Tim Cunningham, Girish Duvvuri, Jeremy J. Drake | Summary: One of the key research themes identified by the Astro2020 decadal survey is Worlds and Suns in Context. The Advanced X-ray Imaging Satellite (AXIS) is a proposed NASA APEX mission that will […]

Kavli Affiliate: Erin Kara | First 5 Authors: The AXIS Time-Domain, Multi-Messenger Science Working Group, :, Riccardo Arcodia, Franz E. Bauer | Summary: The Advanced X-ray Imaging Satellite (AXIS) promises revolutionary science in the X-ray and multi-messenger time domain. AXIS will leverage excellent spatial resolution (<1.5 arcsec), sensitivity (80x that of Swift), and a large […]

Kavli Affiliate: Sara Seager | First 5 Authors: Filipe Pereira, Samuel K. Grunblatt, Angelica Psaridi, Tiago L. Campante, Margarida S. Cunha | Summary: In this work we present the discovery and confirmation of two hot Jupiters orbiting red-giant stars, TOI-4377 b and TOI-4551 b, observed by TESS in the southern ecliptic hemisphere and later followed-up […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Fabio La Monaca, Alessandro Di Marco, Juri Poutanen, Matteo Bachetti, Sara E. Motta | Summary: The Imaging X-ray Polarimetry Explorer measured with high significance the X-ray polarization of the brightest Z-source Sco X-1, resulting in the nominal 2-8 keV energy band in a polarization degree of […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Emmanuel Fonseca, Ziggy Pleunis, Daniela Breitman, Ketan R. Sand, Bikash Kharel | Summary: We present a framework for modeling astrophysical pulses from radio pulsars and fast radio bursts (FRBs). This framework, called fitburst, generates synthetic representations of dynamic spectra that are functions of several physical and […]

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Adam Ingram, Niek Bollemeijer, Alexandra Veledina, Michal Dovciak, Juri Poutanen | Summary: We report on a campaign on the bright black hole X-ray binary Swift J1727.8$-$1613 centered around five observations by the Imaging X-ray Polarimetry Explorer (IXPE). This is the first time it has been possible […]
