Composition of Terrestrial Exoplanet Atmospheres from Meteorite Outgassing Experiments

Posted by klaurent April 16, 2021Stanford

Kavli Affiliate: Laura Schaefer | First 5 Authors: Maggie A. Thompson, Myriam Telus, Laura Schaefer, Jonathan J. Fortney, Toyanath Joshi | Summary: Terrestrial exoplanets likely form initial atmospheres through outgassing during and after accretion, although there is currently no first-principles understanding of how to connect a planet’s bulk composition to its early atmospheric properties. Important […]

Design and performance of a multi-terahertz Fourier transform spectrometer for axion dark matter experiments

Posted by April 14, 2021Chicago

Kavli Affiliate: Clarence Chang | First 5 Authors: Kristin Dona, Jesse Liu, Noah Kurinsky, David Miller, Pete Barry | Summary: Dedicated spectrometers for terahertz radiation with [0.3, 30] THz frequencies using traditional optomechanical interferometry are substantially less common than their infrared and microwave counterparts. This paper presents the design and initial performance measurements of a […]

Mass and Environment as Drivers of Galaxy Evolution. IV. On the Quenching of Massive Central Disk Galaxies in The Local Universe

Posted by klaurent April 14, 2021Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Chengpeng Zhang, Yingjie Peng, Luis C. Ho, Roberto Maiolino, Alvio Renzini | Summary: The phenomenological study of evolving galaxy populations has shown that star forming galaxies can be quenched by two distinct processes: mass quenching and environment quenching (Peng et al. 2010). To explore the mass quenching […]

Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). XIII. Large-scale Feedback and Star Formation in a Low-Luminosity Quasar at z = 7.07 on the Local Black Hole to Host Mass Relation

Posted by April 12, 2021Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Takuma Izumi, Yoshiki Matsuoka, Seiji Fujimoto, Masafusa Onoue, Michael A. Strauss | Summary: We present ALMA [CII] 158 $mu$m line and underlying far-infrared (FIR) continuum emission observations ($0”.70 times 0”.56$ resolution) toward HSC J124353.93$+$010038.5 (J1243$+$0100) at $z = 7.07$, the only low-luminosity ($M_{rm 1450} > -25$ […]

The stellar mass in and around isolated central galaxies: connections to the total mass distribution through galaxy-galaxy lensing in the Hyper Suprime-Cam survey

Posted by klaurent April 12, 2021Tokyo

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Wenting Wang, Xiangchong Li, Jingjing Shi, Jiaxin Han, Naoki Yasuda | Summary: Using photometric galaxies from the HSC survey, we measure the stellar mass density profiles for satellite galaxies as a function of the projected distance, $r_p$, to isolated central galaxies (ICGs) selected from SDSS/DR7 spectroscopic galaxies […]

Cosmological Evolution of Fermi-LAT Gamma-ray Blazars Using Novel Nonparametric Methods

Posted by klaurent April 10, 2021Stanford

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Houdun Zeng, Vahé Petrosian, Tingfeng Yi, , | Summary: Multi-wavelength analyses of spectra of active galactic nuclei (AGNs) provide useful information on the physical processes in the accretion disk and jets of black holes. This, however, is limited to bright sources and may not represent the population […]

Measurement of the Ionization Yield of Neutron-Induced Proton Recoils in Tetramethylsilane

Posted by klaurent April 10, 2021Stanford

Kavli Affiliate: Giorgio Gratta | First 5 Authors: Shuoxing Wu, Brian Lenardo, Giorgio Gratta, , | Summary: We report on a low energy measurement of the ionization yield in a Tetramethylsilane Time Projection Chamber (TPC) using 2.8 MeV neutrons from a deuterium-deuterium neutron generator. The proton recoil charge yield is measured at four different electric […]

Correcting correlation functions for redshift-dependent interloper contamination

Posted by klaurent April 9, 2021Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Daniel J. Farrow, Ariel G. Sánchez, Robin Ciardullo, Erin Mentuch Cooper, Dustin Davis | Summary: The construction of catalogues of a particular type of galaxy can be complicated by interlopers contaminating the sample. In spectroscopic galaxy surveys this can be due to the misclassification of an emission […]

FastEMRIWaveforms: New tools for millihertz gravitational-wave data analysis

Posted by klaurent April 9, 2021MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Michael L. Katz, Alvin J. K. Chua, Lorenzo Speri, Niels Warburton, Scott A. Hughes | Summary: We present the FastEMRIWaveforms (FEW) package, a collection of tools to build and analyze extreme mass ratio inspiral (EMRI) waveforms. Here, we expand on the Physical Review Letter that introduced […]
