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 Tokyo

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 […]

Topological Dissipation in a Time-Multiplexed Photonic Resonator Network

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | First 5 Authors: Christian Leefmans, Avik Dutt, James Williams, Luqi Yuan, Midya Parto | Summary: Topological phases feature robust edge states that are protected against the effects of defects and disorder. The robustness of these states presents opportunities to design technologies that are tolerant to fabrication errors and resilient to […]

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

Posted by klaurent Stanford

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 Stanford

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 Tokyo

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 […]
