The Ages of Optically Bright Sub-Clusters in the Serpens Star-Forming Region

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Xingyu Zhou, Gregory J. Herczeg, Yao Liu, Min Fang, Michael Kuhn | Summary: The Serpens Molecular Cloud is one of the most active star-forming regions within 500 pc, with over one thousand of YSOs at different evolutionary stages. The ages of the member stars inform us […]

High-precision temperature monitoring system for room-temperature equipment in astrophysical observations

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: Daiki Tanabe, Masaya Hasegawa, Masashi Hazumi, Nobuhiko Katayama, Shuhei Kikuchi | Summary: We present a precise thermometry system to monitor room-temperature components of a telescope for radio-astronomy such as cosmic microwave background (CMB) observation. The system realizes precision of 1 mK${rm sqrt{s}}$ on a timescale of 20 […]

On the Cosmology of Dirac-Born-Infeld dRGT Massive Gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Sobhan Kazempour, Amin Rezaei Akbarieh, Hossein Motavalli, Lijing Shao, | Summary: We introduce the cosmological analysis of the Dirac-Born-Infeld dRGT massive gravity theory which is a new extended of de Rham-Gabadadze-Tolley (dRGT) massive gravity. In this theory, we consider the Dirac-Born-Infeld (DBI) scalar field which is coupled […]

Plasmon-molecule remote coupling via column-structured silica layer for enhancing biophotonic analysis

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Takeo Minamikawa, Reiko Sakaguchi, Yoshinori Harada, Hideharu Hase, Yasuo Mori | Summary: We demonstrated remote plasmonic enhancement (RPE) by a dense random array of Ag nanoislands (AgNIs) that were partially gold-alloyed and attached with column-structured silica (CSS) overlayer of more than 100 nm in thickness. The physical […]

Formation of episodic jets and associated flares from black hole accretion systems

Kavli Affiliate: Feng Yuan | First 5 Authors: Miljenko Cemeljic, Hai Yang, Feng Yuan, Hsien Shang, | Summary: Episodic ejections of blobs (episodic jets) are widely observed in black hole sources and usually associated with flares. In this paper, by performing and analyzing three dimensional general relativity magnetohydrodynamical numerical simulations of accretion flows, we investigate […]
