Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yasunori Lee, Yuji Tachikawa, , , | Summary: Global gauge anomalies in $6d$ associated with non-trivial homotopy groups $pi_6(G)$ for $G=SU(2)$, $SU(3)$, and $G_2$ were computed and utilized in the past. In the modern bordism point of view of anomalies, however, they come from the bordism groups […]
Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Peter Bult, Diego Altamirano, Zaven Arzoumanian, Anna V. Bilous, Deepto Chakrabarty | Summary: In this work we report on observations with the Neutron Star Interior Composition Explorer of the known neutron star X-ray transient XTE J1739-285. We observed the source in 2020 February and March, finding it […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Thomas Essinger-Hileman, Trevor Oxholm, Gage Siebert, Peter Ade, Christopher Anderson | Summary: This work describes the optical design of the EXperiment for Cryogenic Large-Aperture Intensity Mapping (EXCLAIM). EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide (CO) at redshifts z < 1 […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Thomas Essinger-Hileman, Trevor Oxholm, Gage Siebert, Alyssa Barlis, Emily M. Barrentine | Summary: This work describes the design and implementation of optics for EXCLAIM, the EXperiment for Cryogenic Large-Aperture Intensity Mapping. EXCLAIM is a balloon-borne telescope that will measure integrated line emission from carbon monoxide (CO) at […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Yang Huang, Qingzheng Li, Huawei Zhang, Xinyi Li, Weixiang Sun | Summary: In this letter, we report the discovery of an intriguing HVS (J1443+1453) candidate that is probably from the Sagittarius Dwarf Spheroidal galaxy (Sgr dSph). The star is an old and very metal-poor low-mass main-sequence turn-off […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Lea A. Hirsch, Lee Rosenthal, Benjamin J. Fulton, Andrew W. Howard, David R. Ciardi | Summary: We explore the impact of outer stellar companions on the occurrence rate of giant planets detected with radial velocities. We searched for stellar and planetary companions to a volume-limited sample of […]
Kavli Affiliate: Erin Kara | First 5 Authors: Michael McDonald, Brian R. McNamara, Michael S. Calzadilla, Chien-Ting Chen, Massimo Gaspari | Summary: We present a study of the relationship between black hole accretion rate (BHAR) and star formation rate (SFR) in a sample of giant elliptical galaxies. These galaxies, which live at the centers of […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Philip Clarke, E. P. S. Shellard, , , | Summary: Calculating the primordial bispectrum predicted by a model of inflation and comparing it to what we see in the sky is very computationally intensive, necessitating layers of approximations and limiting the models which can be […]
