DM+ simulations with DMSimp: an update
Yoav Afik, Fabio Maltoni, Kentarou Mawatari +4
Searches for dark matter (DM) produced using collider data probe wide regions of the allowed parameter space of many models and have become competitive with more traditional search…
Detections of [OIII] 88 m in Two Quasars in the Reionization Epoch
Takuya Hashimoto, Akio K. Inoue, Yoichi Tamura +3
With the Atacama Large Millimeter/sub-millimeter Array (ALMA), we report detections of the far-infrared (FIR) [OIII] 88 m line and the underlying dust continuum in the two quasa…
Single Higgs production in association with a photon at electron-positron colliders in extended Higgs models
Shinya Kanemura, Kentarou Mawatari, Kodai Sakurai
We study associated Higgs production with a photon at electron-positron colliders, , in various extended Higgs models, such as the inert doublet model (IDM), the iner…
Detection of the Far-infrared [O III] and Dust Emission in a Galaxy at Redshift 8.312: Early Metal Enrichment in the Heart of the Reionization Era
Yoichi Tamura, Ken Mawatari, Takuya Hashimoto +19
We present the Atacama Large Millimeter/submillimeter Array (ALMA) detection of the [O III] 88 m line and rest-frame 90 m dust continuum emission in a Y-dropout Lyman break g…
"Big Three Dragons": a z = 7.15 Lyman BreakGalaxy Detected in [OIII] 88 m, [CII] 158 m, and Dust Continuum with ALMA
Takuya Hashimoto, Akio K. Inoue, Ken Mawatari +18
We present new ALMA observations and physical properties of a Lyman Break Galaxy at z=7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, $M_{\rm UV}\ap…
The onset of star formation 250 million years after the Big Bang
Takuya Hashimoto, Nicolas Laporte, Ken Mawatari +21
A fundamental quest of modern astronomy is to locate the earliest galaxies and study how they influenced the intergalactic medium a few hundred million years after the Big Bang. Th…
CHORUS II. Subaru/HSC Determination of the Ly Luminosity Function at : Constraints on Cosmic Reionization Model Parameter
Ryohei Itoh, Masami Ouchi, Haibin Zhang +16
We present the Ly luminosity function (LF) derived from 34 Ly emitters (LAEs) at on the sky of deg, the largest sample compared to those in the literature o…
Loop effects on the Higgs decay widths in extended Higgs models
Shinya Kanemura, Mariko Kikuchi, Kentarou Mawatari +2
In order to identify the Higgs sector using future precision data, we calculate the partial decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs a…
