Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Tansu Daylan, Natalia Guerrero, William Fong, Steve Bryson | Summary: We present the detection of 1,617 new transiting planet candidates, identified in the Transiting Exoplanet Survey Satellite (TESS) full-frame images (FFIs) observed during the Primary Mission (Sectors 1 – 26). These candidates were initially detected […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Han-Ji Wu, Guo-Bin Mou, Kai Wang, Wei Wang, Zhuo Li | Summary: The origin of ultra-high energy neutrinos still lacks observational evidence, besides, the physical mechanism is also unclear. There is an association of a PeV neutrino event (IceCube-191001A) with an optical tidal disruption event (TDE, AT2019dsg) […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Elena M. Murchikova, Tianshu Wang, Brian Mason, Roger D. Blandford, | Summary: Murchikova et al 2019 discovered a disk of cool ionized gas within 20,000 Schwarzschild radii of the Milky Way’s Galactic Center black hole Sagittarius A*. They further demonstrated that the ionizing photon flux in […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: John F. Wu, J. E. G. Peek, Erik J. Tollerud, Yao-Yuan Mao, Ethan O. Nadler | Summary: We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low-$z$ galaxies on the basis of optical imaging, and results on the spatial distributions of […]
Kavli Affiliate: Richard Kessler | First 5 Authors: Anthony Carr, Tamara M. Davis, Daniel Scolnic, Khaled Said, Dillon Brout | Summary: We examine the redshifts of a comprehensive set of published Type Ia supernovae, and provide a combined, improved catalog with updated redshifts. We improve on the original catalogs by using the most up-to-date heliocentric […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Kristine W. F. Lam, Szilárd Csizmadia, Nicola Astudillo-Defru, Xavier Bonfils, Davide Gandolfi | Summary: Ultra-short-period (USP) exoplanets have orbital periods shorter than one day. Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]

Precise masses and radii of USPs could provide constraints on their unknown formation and evolution processes. We report the detection and characterization […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Martin C. Weisskopf, Paolo Soffitta, Luca Baldini, Brian D. Ramsey, Stephen L. O’Dell | Summary: Scheduled to launch in late 2021, the Imaging X-ray Polarimetry Explorer (IXPE) is a NASA Small Explorer Mission in collaboration with the Italian Space Agency (ASI). The mission will open a […]
Kavli Affiliate: Donald G. York | First 5 Authors: Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka, Donald G. York, Neeraj Gupta | Summary: We report {it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02$<$$z$$<$ 0.14 within impact parameters of $sim$1-7 kpc. We detect damped/sub-damped Ly$alpha$ absorption in 100$%$ of […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. P. Filippini, A. E. Gambrel, A. S. Rahlin, E. Y. Young, P. A. R. Ade | Summary: Experiments deploying large arrays of transition-edge sensors (TESs) often require a robust method to monitor gain variations with minimal loss of observing time. We propose a sensitive and […]
