Photometric variability of the pre-main sequence stars towards the Sh 2-190 region
Tirthendu Sinha, Saurabh Sharma, Neelam Panwar +7
We present the results from our time-series imaging data taken with the 1.3m Devasthal fast optical telescope and 0.81m Tenagara telescope in , , bands covering a…
Wide and Deep Exploration of Radio Galaxies with Subaru HSC (WERGS). III. Discovery of a z = 4.72 Radio Galaxy with Lyman Break Technique
Takuji Yamashita, Tohru Nagao, Hiroyuki Ikeda +17
We report a discovery of radio galaxy, HSC J083913.17+011308.1, by using the Lyman break technique with the Hyper Suprime-Cam Subaru Strategic Survey (HSC-SSP) catalog f…
Quantifying the effect of field variance on the H luminosity function with the New Numerical Galaxy Catalogue (GC)
Kazuyuki Ogura, Masahiro Nagashima, Rhythm Shimakawa +9
We construct a model of H emitters (HAEs) based on a semi-analytic galaxy formation model, the New Numerical Galaxy Catalog (GC). In this paper, we report our estimate for…
ALMA band 8 observations of DLA2233+131 at z=3.150
Kazuyuki Ogura, Hideki Umehata, Yoshiaki Taniguchi +8
We present our ALMA Band 8 observations of a damped Ly absorption (DLA) system at =3.150 observed in the spectrum of the quasar Q2233+131 at =3.295. The optical counterpar…
A search for Ly-alpha emitters around a concentrated-region of strong Ly-alpha absorbers at z=2.3
Kazuyuki Ogura, Tohru Nagao, Masatoshi Imanishi +6
In order to investigate the physical relationship between strong Ly-alpha absorbers (logN_HI>20.0 cm^-2) such as damped Ly-alpha absorption systems (DLAs) and young star-forming ga…
Study of Negative and Positive Superhumps in ER Ursae Majoris
Tomohito Ohshima, Taichi Kato, Elena Pavlenko +45
We carried out the photometric observations of the SU UMa-type dwarf nova ER UMa during 2011 and 2012, which showed the existence of persistent negative superhumps even during the…
Multi-Color Photometry of the Outburst of the New WZ Sge-type Dwarf Nova, OT J012059.6+325545
Shinichi Nakagawa, Ryo Noguchi, Eriko Iino +5
We present our photometric studies of the newly discovered optical transient, OT J012059.6+325545, which underwent a large outburst between 2010 November and 2011 January. The ampl…
