Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, , , | Summary: The use of galaxy clusters as cosmological probes often relies on understanding the properties and evolution of the intracluster medium (ICM). However, the ICM is a complex plasma, regularly stirred by mergers and feedback, with non-negligible bulk and […]
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, […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quadruply lensed quasars are visible only when the source quasar lies within the diamond caustic of the lensing galaxy. This condition creates a Malmquist-like selection effect in the population of observed quadruply lensed quasars, increasing the true […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Derek Baldwin, Paul L. Schechter, , , | Summary: Quasars are quadruply lensed only when they lie within the diamond caustic of a lensing galaxy. This precondition produces a Malmquist-like selection effect in observed populations of quadruply lensed quasars, overestimating the true caustic area. The bias […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kaname Imagawa, Masahiro Kawasaki, Kai Murai, Hiromasa Nakatsuka, Eisuke Sonomoto | Summary: Axion-like particles (ALPs) are pseudoscalar bosons predicted by string theory. The ALPs have a shallower potential than a quadratic one, which induces the instability and can form the solitonic object called oscillon/I-ball. Although the lifetime […]
Kavli Affiliate: Jia Liu | First 5 Authors: Tianxiang Gao, Hailiang Liu, Jia Liu, Hridesh Rajan, Hongyang Gao | Summary: Implicit deep learning has received increasing attention recently due to the fact that it generalizes the recursive prediction rules of many commonly used neural network architectures. Its prediction rule is provided implicitly based on the […]
Kavli Affiliate: George Ricker | First 5 Authors: Michelle Kunimoto, Chelsea Huang, Evan Tey, Willie Fong, Katharine Hesse | Summary: We present a magnitude-limited set of lightcurves for stars observed over the TESS Extended Mission, as extracted from full-frame images (FFIs) by MIT’s Quick-Look Pipeline (QLP). QLP uses multi-aperture photometry to produce lightcurves for ~1 […]
