Kavli Affiliate: Gabor Furesz | First 5 Authors: Veselin B. Kostov, Brian P. Powell, Jerome A. Orosz, William F. Welsh, William Cochran | Summary: We report the first discovery of a transiting circumbinary planet detected from a single sector of TESS data. During Sector 21, the planet TIC 172900988b transited the primary star and then […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Hiromasa Nakatsuka, Kazunori Nakayama, Toyokazu Sekiguchi, | Summary: The precision measurements of the cosmic microwave background power spectrum put a strong constraint on the dark matter annihilation cross section since the electromagnetic energy injection by the dark matter annihilation affects the ionization history of the […]
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: Satoshi Shirai | First 5 Authors: Taisuke Katayose, Shigeki Matsumoto, Satoshi Shirai, Yu Watanabe, | Summary: Real scalar triplet dark matter, which is known to be an attractive candidate for a thermal WIMP, is comprehensively studied paying particular attention to the Sommerfeld effect on the dark matter annihilation caused by the weak interaction […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Maria Giovanna Dainotti, Nicola Omodei, Gokul . P. Srinivasaragavan, Giacomo Vianello, Richard Willingale | Summary: The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afterglows observed by the Neil Gehrels Swift […]
Kavli Affiliate: Xian Chen | First 5 Authors: Chenbo Zhang, Zhuohui Zeng, Zeyuan Zhu, Nobumichi Tamura, Xian Chen | Summary: Searching for performant multiferroic materials attracts general research interests in energy science as they have been increasingly exploited as the conversion media among thermal, electric, magnetic and mechanical energies by using their temperature-dependent ferroic properties. […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Anh Phan, Santanu Das, Albert Stebbins, Peter Timbie, Reza Ansari | Summary: Hydrogen intensity mapping is a new field in astronomy that promises to make three-dimensional maps of the matter distribution of the Universe using the redshifted $21,textrm{cm}$ line of neutral hydrogen gas (HI). Several ongoing and […]
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: Rainer Spurzem | First 5 Authors: Manuel Arca Sedda, Francesco Paolo Rizzuto, Thorsten Naab, Jeremiah Ostriker, Mirek Giersz | Summary: The LIGO-Virgo-Kagra collaboration (LVC) discovered recently GW190521, a gravitational wave (GW) source associated with the merger between two black holes (BHs) with mass $66$ M$_odot$ and $>85$ M$_odot$. GW190521 represents the first BH […]
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 […]
