Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys
Tomomi Sunayama, Masahiro Takada, Martin Reinecke +6
We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys. We identify new effects which were absent in previous, relatively…
Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs). X. Discovery of 35 Quasars and Luminous Galaxies at 5.7 z 7.0
Yoshiki Matsuoka, Kazushi Iwasawa, Masafusa Onoue +44
We report the discovery of 28 quasars and 7 luminous galaxies at 5.7 z 7.0. This is the tenth in a series of papers from the Subaru High-z Exploration of Low-Luminosity…
SpecTel: A 10-12 meter class Spectroscopic Survey Telescope
Richard Ellis, Kyle Dawson, Joss Bland-Hawthorn +25
We recommend a conceptual design study for a spectroscopic facility in the southern hemisphere comprising a large diameter telescope, fiber system, and spectrographs collectively o…
Cosmological information content in redshift-space power spectrum of SDSS-like galaxies in the quasi-nonlinear regime up to Mpc
Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada +1
Clustering properties and peculiar velocities of halos in large-scale structure carry a wealth of cosmological information over a wide range of scales from linear to nonlinear scal…
Constraining dark matter annihilation with HSC Low Surface Brightness Galaxies
Daiki Hashimoto, Oscar Macias, Atsushi J. Nishizawa +4
Searches for dark matter annihilation signals have been carried out in a number of target regions such as the Galactic Center and Milky Way dwarf spheroidal galaxies (dSphs), among…
Cosmological constraints from cosmic shear two-point correlation functions with HSC survey first-year data
T. Hamana, M. Shirasaki, S. Miyazaki +17
We present measurements of cosmic shear two-point correlation functions (TPCFs) from Hyper Suprime-Cam Subaru Strategic Program (HSC SSP) first-year data, and derived cosmological…
