We present results of the cross-correlation analysis between active galactic
nuclei (AGNs) and galaxies at redshift 0.1-1. We obtain data of ~10,000 SDSS
AGNs in which their virial masses with a super-massive black hole (SMBH) were
estimated. The ...

ALMA is estimated to generate TB scale data during only one observation;
astronomers manage to identify which part of the data they are really
interested in. Now we have been developing new GUI software for this purpose
utilizing the VO interface:...

This document describes the Astronomical Data Query Language (ADQL). ADQL has
been developed based on SQL92. This document describes the subset of the SQL
grammar supported by ADQL. Special restrictions and extensions to SQL92 have
been defined in...

We present the result of projected cross correlation analysis of AGNs and
galaxies at redshifts from 0.3 to 3.0. The Japanese Virtual Observatory (JVO)
was used to obtain the Subaru Suprime-Cam images and UKIDSS catalog data around
AGNs. We invest...

We present results of a survey of CCS, HCTexN, and HCTexN toward 40
dark cloud cores to search for "Carbon-Chain--Producing Regions(CCPRs)", where
carbon-chain molecules are extremely abundant relative to NHTex, as in
L1495B, L1521B, L152...
