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 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 […]

A Uniform Search for Nearby Planetary Companions to Hot Jupiters in TESS Data Reveals Hot Jupiters are Still Lonely

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Benjamin J. Hord, Knicole D. Colón, Veselin Kostov, Brianna Galgano, George R. Ricker | Summary: We present the results of a uniform search for additional planets around all stars with confirmed hot Jupiters observed by the Transiting Exoplanet Survey Satellite (TESS) in its Cycle 1 survey of […]
