Census of R Coronae Borealis stars I: Infrared light curves from Palomar Gattini IR
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +16
We are undertaking the first systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, beginning with IR light curves from the Palomar Gattini IR (PGIR) s…
Reduction of quantum noise using the quantum locking with an optical spring for gravitational wave detectors
Rika Yamada, Yutaro Enomoto, Izumi Watanabe +11
In our previous research, simulation showed that a quantum locking scheme with homodyne detection in sub-cavities is effective in surpassing the quantum noise limit for Deci-hertz…
Direct Measurement of the Cosmic-Ray Carbon and Oxygen Spectra from 10 GeV to 2.2 TeV with the Calorimetric Electron Telescope on the International Space Station
O. Adriani, Y. Akaike, K. Asano +81
In this paper, we present the measurement of the energy spectra of carbon and oxygen in cosmic rays based on observations with the Calorimetric Electron Telescope (CALET) on the In…
Nature of bright C-complex asteroids
Sunao Hasegawa, Toshihiro Kasuga, Fumihiko Usui +1
Most C-complex asteroids have albedo values less than 0.1, but there are some high-albedo (bright) C-complex asteroids with albedo values exceeding 0.1. To reveal the nature and or…
Assessment of Cr isotopic heterogeneities of volatile-rich asteroids based on multiple planet formation models
Ryota Fukai, Sota Arakawa
Describing the comprehensive evolutionary scenario for asteroids is key to explaining the various physical processes of the solar system. Bulk-scale carbonaceous chondrites (CCs) p…
Photometric Redshifts in the North Ecliptic Pole Wide Field based on a Deep Optical Survey with Hyper Suprime-Cam
Simon C. -C. Ho, Tomotsugu Goto, Nagisa Oi +13
The space infrared telescope has performed near- to mid-infrared (MIR) observations on the North Ecliptic Pole Wide (NEPW) field (5.4 deg) for about one year. t…
