AKARIFar-Infrared all sky survey [PDF]
SPICA joint European/Japanese Workshop, 2009 We demonstrate the capability of AKARI for mapping diffuse far-infrared emission and achieved reliability of all-sky diffuse map. We have conducted an all-sky survey for more than 94 % of the whole sky during cold phase of AKARI observation in 2006 Feb. -- 2007 Aug.

Discovery of 21 New Changing-look AGNs in the Northern Sky [PDF]
Astrophysical Journal, 2017 The rare case of changing-look (CL) active galactic nuclei (AGNs), with the appearance or disappearance of broad Balmer emission lines within a few years, challenges our understanding of the AGN unified model.

THE SLOAN DIGITAL SKY SURVEY-II SUPERNOVA SURVEY: TECHNICAL SUMMARY [PDF]
The Astronomical Journal, 2007 The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (SNe Ia) using repeated five-band (ugriz) imaging over an area of 300 sq. deg.

Detection of Earth-impacting asteroids with the next generation all-sky surveys [PDF]
, 2009 We have performed a simulation of a next generation sky survey’s (Pan-STARRS 1) efficiency for detecting Earth-impacting asteroids. The steady-state sky-plane distribution of the impactors long before impact is concentrated towards small solar ...

The Sloan Digital Sky Survey Reverberation Mapping Project: Sample Characterization [PDF]
Astrophysical Journal Supplement Series, 2018 We present a detailed characterization of the 849 broad-line quasars from the Sloan Digital Sky Survey Reverberation Mapping (SDSS-RM) project. Our quasar sample covers a redshift range of 0.1 < z < 4.5 and is flux-limited to iPSF < 21.7 without any ...

Cosmic core-collapse supernovae from upcoming sky surveys [PDF]
, 2009 Large synoptic (repeated scan) imaging sky surveys are poised to observe enormous numbers of core-collapse supernovae. We quantify the discovery potential of such surveys, and apply our results to upcoming projects, including DES, Pan-STARRS, and LSST ...

The LOFAR Two-metre Sky Survey [PDF]
Astronomy & Astrophysics, 2018 The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120–168 MHz survey of the entire northern sky for which observations are now 20% complete. We present our first full-quality public data release.
