Report of the Topical Group on Cosmic Probes of Fundamental Physics for for Snowmass 2021

Kavli Affiliate: David H. Shoemaker | First 5 Authors: Rana X. Adhikari, Luis A. Anchordoqui, Ke Fang, B. S. Sathyaprakash, Kirsten Tollefson | Summary: Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probes give access to fundamental physics […]

TESS discovery of a super-Earth and two sub-Neptunes orbiting the bright, nearby, Sun-like star HD 22946

Kavli Affiliate: Avi Shporer | First 5 Authors: Luca Cacciapuoti, Laura Inno, Giovanni Covone, Veselin B. Kostov, Thomas Barclay | Summary: We report the Transiting Exoplanet Survey Satellite (TESS) discovery of a three-planet system around the bright Sun-like star HD~22946(V=8.3 mag),also known as TIC~100990000, located 63 parsecs away.The system was observed by TESS in Sectors […]

Spin it as you like: the (lack of a) measurement of the spin tilt distribution with LIGO-Virgo-KAGRA binary black holes

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Salvatore Vitale, Sylvia Biscoveanu, Colm Talbot, , | Summary: The growing set of gravitational-wave sources is being used to measure the properties of the underlying astrophysical populations of compact objects, black holes and neutron stars. Most of the detected systems are black hole binaries. While much has […]

Polarized Blazar X-rays imply particle acceleration in shocks

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Blazars are active galactic nuclei that launch collimated, powerful jets of magnetized relativistic plasma. Their primary jet, whose emission typically spans from low-frequency radio to very high-energy ($gtrsim0.1$ TeV) $gamma$-rays (Blandford […]

Polarized Blazar X-rays imply particle acceleration in shocks

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $sim 1$ […]

Stellar Bars in Isolated Gas-Rich Spiral Galaxies Do Not Slow Down

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Angus Beane, Lars Hernquist, Elena D’Onghia, Federico Marinacci, Charlie Conroy | Summary: Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks. Due to gravitational interactions between the bar and the other components of galaxies, it is expected that angular […]

The X-ray polarimetry view of the accreting pulsar Cen X-3

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Sergey S. Tsygankov, Victor Doroshenko, Juri Poutanen, Jeremy Heyl, Alexander A. Mushtukov | Summary: Cen X-3 is the first X-ray pulsar discovered 50 years ago. Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with propagation of […]
