Kavli Affiliate: Albert Stebbins | First 5 Authors: Christina Gao, Albert Stebbins, , , | Summary: In this paper we study how a Yukawa coupling of the Standard Model fermions to a light scalar field effects the stellar structure of cold stellar remnants such as neutron stars. We elucidate the stellar structure phenomenology using a […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada, Hironao Miyatake, | Summary: We present the results obtained from the full-shape cosmology analysis of the redshift-space power spectra for 4 galaxy samples of the SDSS-III BOSS DR12 galaxy catalog over $0.2 < z < 0.75$. For the theoretical template, we […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Ting S. Li, Alexander P. Ji, Andrew B. Pace, Denis Erkal, Sergey E. Koposov | Summary: We report the kinematic, orbital, and chemical properties of 12 stellar streams with no evident progenitors, using line-of-sight velocities and metallicities from the Southern Stellar Stream Spectroscopic Survey ($S^5$), proper […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Nicholas Scarsdale, Joseph M. Akana Murphy, Natalie M. Batalha, Ian J. M. Crossfield, Courtney D. Dressing | Summary: We present the discovery of two nearly identically-sized sub-Neptune transiting planets orbiting HD 63935, a bright ($V=8.6$ mag), sun-like ($T_{eff}=5560K$) star at 49 pc. TESS identified the first planet, […]
