The new generation of spectrometers designed for extreme precision radial velocities enable correspondingly precise stellar spectroscopy. It is now fruitful to...
Identifying Missing Quasars from the DESI Bright Galaxy Survey
The Dark Energy Spectroscopic Instrument (DESI) cosmology survey includes a Bright Galaxy Survey (BGS), which will yield spectra for over 10 million bright...
Improved method of hydrous mineral detection by latitudinal distribution of 0.7-μm surface reflectance absorption on the asteroid Ryugu
Global multiband images of the C-type asteroid (162173) Ryugu were obtained by the optical navigation camera telescope (ONC-T) onboard Hayabusa2. The 0.7-μm...
We present the results of our observations of stars of type O5 and earlier and show that inclusion of the line blocking between 228 and 912 A solves the problem...
JWST view of Polycyclic Aromatic Hydrocarbons and dust in local active galaxies
Nowadays, it is widely accepted that most galaxies undergo an active phase in their evolution. The impact of the energy released by active galactic nuclei (AGN)...
LEMUR: Large European module for solar Ultraviolet Research. European contribution to JAXA's Solar-C mission
The solar outer atmosphere is an extremely dynamic environment characterized by the continuous interplay between the plasma and the magnetic field that...
Light curves of SDSS J100658.40+233724.4 (Southworth+, 2009)
We present the discovery and follow-up observations of eclipses of the cataclysmic variable star SDSS J100658.40+233724.4, fom which we determine the orbital...
Line intensities of SDSS HII regions (Pilyugin+, 2010)
Spectra of high-metallicity [12+log(O/H)>~8.2] HII regions, where oxygen auroral lines are measurable in both the O+ and O++ zones, have been extracted from the...
