The intrinsic structure of Sagittarius A* at 1.3 cm and 7 mm
Ilje Cho, Guang-Yao Zhao, Tomohisa Kawashima +63
Sagittarius A* (Sgr A*), the Galactic Center supermassive black hole (SMBH), is one of the best targets to resolve the innermost region of SMBH with very long baseline interferomet…
Non-resonant new physics search at the LHC for the anomalies
Motoi Endo, Syuhei Iguro, Teppei Kitahara +2
Motivated by the anomalies, we study non-resonant searches for new physics at the large hadron collider (LHC) by considering final states with an energetic an…
Second Epoch ALMA Observations of 321 GHz Water Maser Emission in NGC 4945 and the Circinus Galaxy
Yoshiaki Hagiwara, Shinji Horiuchi, Masatoshi Imanishi +1
We present the results of second epoch ALMA observations of 321 GHz HO emission toward two nearby active galactic nuclei, NGC 4945 and the Circinus galaxy, together with Tidbin…
East Asian VLBI Network Observations of Active Galactic Nuclei Jets: Imaging with KaVA+Tianma+Nanshan
Yuzhu Cui, Kazuhiro Hada, Motoki Kino +74
The East Asian very-long-baseline interferometry (VLBI) Network (EAVN) is a rapidly evolving international VLBI array that is currently promoted under joint efforts among China, Ja…
Variations of Ramanujan's Euler Products
Shin-ya Koyama, Nobushige Kurokawa
We study the meromorphy of various Euler products of degree two attached to cusp forms including Ramanujan's -function.
ALMA detection of millimetre 183 GHz H2O maser emission in the Superantennae galaxy at z ~ 0.06
Masatoshi Imanishi, Yoshiaki Hagiwara, Shinji Horiuchi +2
We present the results of ALMA band-5 (~170 GHz) observations of the merging ultraluminous infrared galaxy, the "Superantennae" (IRAS 19254-7245) at z=0.0617, which has been diagno…
