The Compton Spectrometer and Imager Project for MeV Astronomy

Kavli Affiliate: Tom Melia | First 5 Authors: John A. Tomsick, Steven E. Boggs, Andreas Zoglauer, Eric Wulf, Lee Mitchell | Summary: The Compton Spectrometer and Imager (COSI) is a 0.2-5 MeV Compton telescope capable of imaging, spectroscopy, and polarimetry of astrophysical sources. Such capabilities are made possible by COSI’s germanium cross-strip detectors, which provide […]

Hyper Suprime-Cam Subaru Strategic Program: A Mass-Dependent Slope of the Galaxy Size-Mass Relation at $z<1$

Kavli Affiliate: John D. Silverman | First 5 Authors: Lalitwadee Kawinwanichakij, John D. Silverman, Xuheng Ding, Angelo George, Ivana Damjanov | Summary: We present the galaxy size-mass ($R_{e}-M_{ast}$) distributions using a stellar-mass complete sample of $sim1.5$ million galaxies, covering $sim100$ deg$^2$, with $log(M_{ast}/M_{odot})>10.2~(9.2)$ over the redshift range $0.2<z<1.0$ $(z<0.6)$ from the second public data release […]

Dark matter constraint with gamma-ray galaxies cross correlation scales with N

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: A new method to constrain the dark matter annihilation cross section by taking the cross correlation of gamma-ray diffuse maps and galaxies is proposed. As a result, the statistical power of constraining the annihilation cross section […]

Dark matter constraints with stacked gamma rays scales with the number of galaxies

Kavli Affiliate: Masahiro Takada | First 5 Authors: Daiki Hashimoto, Atsushi J. Nishizawa, Masahiro Takada, Oscar Macias, | Summary: Low-surface-brightness galaxies (LSBGs) are interesting targets for searches of dark matter emission due to their low baryonic content. However, predicting their expected dark matter emissivities is difficult because of observational challenges in their distance measurements. Here […]

Dark matter transient annihilations in the early Universe

Kavli Affiliate: Jia Liu | First 5 Authors: Katsuya Hashino, Jia Liu, Xiao-Ping Wang, Ke-Pan Xie, | Summary: The cosmological evolution can modify the dark matter (DM) properties in the early Universe to be vastly different from the properties today. Therefore, the relation between the relic abundance and the DM constraints today needs to be […]
