Electromagnetic Follow-ups of Binary Neutron Star Mergers with Early Warnings from Decihertz Gravitational-wave Observatories

Posted by klaurent May 4, 2022Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Yacheng Kang, Chang Liu, Lijing Shao, , | Summary: We investigate the prospects of electromagnetic follow-ups for binary neutron star (BNS) mergers, with the help of early warnings from decihertz gravitational-wave (GW) observatories, B-DECIGO and DO-Optimal. Extending our previous work in Liu et al. (2022), we not […]

TOI-2046b, TOI-1181b and TOI-1516b, three new hot Jupiters from textit{TESS}: planets orbiting a young star, a subgiant and a normal star

Posted by klaurent May 4, 2022MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Petr Kabáth, Priyanka Chaturvedi, Phillip J. MacQueen, Marek Skarka, Ján Šubjak | Summary: We present the confirmation and characterization of three hot Jupiters, TOI-1181b, TOI-1516b, and TOI-2046b, discovered by the TESS space mission. The reported hot Jupiters have orbital periods between 1.4 and 2.05 days. The masses […]

Posted by klaurent May 3, 2022MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Alexander P. Ji, Mohammad K. Mardini, Xiaowei Ou | Summary: We present chemical abundances and velocities of five stars between 0.3 kpc to 1.1 kpc from the center of the Tucana II ultra-faint dwarf galaxy (UFD) from high-resolution Magellan/MIKE spectroscopy. We find that […]

The effect of the deforming dark matter haloes of the Milky Way and the Large Magellanic Cloud on the Orphan-Chenab stream

Posted by klaurent May 3, 2022May 17, 2022Chicago

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sophia Lilleengen, Michael S. Petersen, Denis Erkal, Jorge Peñarrubia, Sergey E. Koposov | Summary: It has recently been shown that the Large Magellanic Cloud (LMC) has a substantial effect on the Milky Way’s stellar halo and stellar streams. Here, we explore how deformations of the Milky […]

Amplitude modulation in binary gravitational lensing of gravitational waves

Posted by klaurent May 3, 2022Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Yi Qiu, Ke Wang, Jian-hua He, , | Summary: We investigate the detectability of gravitational waves (GWs) lensed by a system that consists of binary black holes as lenses using time-domain numerical simulations. The gravitational lensing potential of this system is no longer static but evolves with […]

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Motoo Suzuki, Keiichi Watanabe, Tsutomu T. Yanagida | Summary: It is remarkable that the matter fields in the Standard Model (SM) are apparently unified into the $mathrm{SU}(5)$ representations. A straightforward explanation of this fact is to embed all the SM gauge groups into […]
