Relationship between Radar Cross Section and Optical Magnitude based on Radar and Optical Simultaneous Observations of Faint Meteors
Ryou Ohsawa, Akira Hirota, Kohei Morita +40
Radar and optical simultaneous observations of meteors are important to understand the size distribution of the interplanetary dust. However, faint meteors detected by high power l…
Environmental impact on star-forming galaxies in a cluster during course of galaxy accretion
Tetsuro Asano, Tadayuki Kodama, Kentaro Motohara +18
Galaxies change their properties as they assemble into clusters. In order to understand the physics behind that, we need to go back in time and observe directly what is occurring i…
An optical search for transients lasting a few seconds
Michael W. Richmond, Masaomi Tanaka, Tomoki Morokuma +37
Using a prototype of the Tomo-e Gozen wide-field CMOS mosaic camera, we acquire wide-field optical images at a cadence of 2 Hz and search them for transient sources of duration 1.5…
New constraint on the atmosphere of (50000) Quaoar from a stellar occultation
Ko Arimatsu, Ryou Ohsawa, George L. Hashimoto +35
We report observations of a stellar occultation by the classical Kuiper belt object (50000) Quaoar occurred on 28 June 2019. A single-chord high-cadence (2 Hz) photometry dataset w…
Ground-based Pa Narrow-band Imaging of Local Luminous Infrared Galaxies II: Bulge Structure And Star Formation Activity
Ken Tateuchi, Kentaro Motohara, Masahiro Konishi +8
We present properties of two types of bulges (classical- and pseudo- bulges) in 20 luminous infrared galaxies (LIRGs) observed in the near infrared of the , and 1.91m n…
Luminosity Function of Faint Sporadic Meteors measured with a Wide-Field CMOS mosaic camera Tomo-e PM
Ryou Ohsawa, Shigeyuki Sako, Yuki Sarugaku +34
Imaging observations of faint meteors were carried out on April 11 and 14, 2016 with a wide-field CMOS mosaic camera, Tomo-e PM, mounted on the 105-cm Schmidt telescope at Kiso Obs…
