Kavli Affiliate: Christopher J. Burke | First 5 Authors: Jennifer A. Burt, Diana Dragomir, Paul Mollière, Allison Youngblood, Antonio García Muñoz | Summary: We report the discovery of a transiting, temperate, Neptune-sized exoplanet orbiting the nearby ($d$ = 27.5 pc), M3V star TOI-1231 (NLTT 24399, L 248-27, 2MASS J10265947-5228099). The planet was detected using photometric […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We prove the equivalence in the covariant phase space of the metric and connection formulations for Palatini gravity, with nonmetricity and torsion, on a spacetime manifold with boundary. To this end, we will […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Thomas E. Riley, Anna L. Watts, Paul S. Ray, Slavko Bogdanov, Sebastien Guillot | Summary: We report on Bayesian estimation of the radius, mass, and hot surface regions of the massive millisecond pulsar PSR J0740$+$6620, conditional on pulse-profile modeling of Neutron Star Interior Composition Explorer X-ray […]
Kavli Affiliate: Erin Kara | First 5 Authors: Edward M. Cackett, Misty C. Bentz, Erin Kara, , | Summary: The central engines of Active Galactic Nuclei (AGNs) are powered by accreting supermassive black holes, and while AGNs are known to play an important role in galaxy evolution, the key physical processes occur on scales that […]
Kavli Affiliate: Erin Kara | First 5 Authors: Erin Kara, Missagh Mehdipour, Gerard A. Kriss, Edward M. Cackett, Nahum Arav | Summary: We present the first results from the ongoing, intensive, multi-wavelength monitoring program of the luminous Seyfert 1 galaxy Mrk 817. While this AGN was, in part, selected for its historically unobscured nature, we […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Martin Greiter, Frank Wilczek, , , | Summary: We propose an exact model of anyon ground states including higher Landau levels, and use it to obtain fractionally quantized Hall states at filling fractions $nu=p/(p(m-1)+1)$ with $m$ odd, from integer Hall states at $nu=p$ through adiabatic localization of […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Gabriele Franciolini, Vishal Baibhav, Valerio De Luca, Ken K. Y. Ng, Kaze W. K. Wong | Summary: With several dozen binary black hole events detected by LIGO/Virgo to date and many more expected in the next few years, gravitational-wave astronomy is shifting from individual-event analyses to population […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Danielle Frostig, John W. Baker, Joshua Brown, Richard S. Burruss, Kristin Clark | Summary: The Wide-field Infrared Transient Explorer (WINTER) is a 1×1 degree infrared survey telescope under development at MIT and Caltech, and slated for commissioning at Palomar Observatory in 2021. WINTER is a seeing-limited infrared […]

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Arghajit Jana, Gaurava K. Jaisawal, Sachindra Naik, Neeraj Kumari, Birendra Chhotaray | Summary: We present detailed timing and spectral studies of the black hole candidate MAXI J0637$-$430 during its 2019-2020 outburst using observations with the {em Neutron Star Interior Composition Explorer (NICER)} and the {em Neil […]
