L/T transition BDs from NIR SpeX spectra
We present a technique to identify spectrophotometrically variable L7-T3 brown dwarfs with single-epoch, low-resolution, near-infrared SpeX spectra. We calculated spectral... -
Spitzer/IRS spectral stacking analysis of GOALS gal.
We present the results of a stacking analysis performed on Spitzer/Infrared Spectrograph high-resolution mid-infrared (mid-IR) spectra of luminous infrared galaxies (LIRGs) in... -
Radio sp. of luminous obscured WISE-NVSS QSOs
We present radio spectra spanning 0.1-10GHz for the sample of heavily obscured luminous quasars with extremely red mid-infrared-optical colors and compact radio emission. The... -
IR-faint WDs from Gaia, NIR phot. and opt. sp.
A recent analysis of the 100pc white dwarf sample in the SDSS footprint demonstrated for the first time the existence of a well-defined ultracool --or IR-faint-- white dwarf... -
Keck/LRIS spectra of PSR J0952-0607
We describe Keck-telescope spectrophotometry and imaging of the companion of the "black widow" pulsar PSR J0952-0607, the fastest known spinning neutron star (NS) in the disk of... -
Catalog of Stellar Flares in 219 M-dwarfs
We present a study of the relationship between Galactic kinematics, flare rates, chromospheric activity, and rotation periods for a volume-complete, nearly all-sky sample of 219... -
2<zobs<4 quasars stacked spectrum
We investigate the metal species associated with the Ly{alpha} forest in eBOSS quasar spectra. Metal absorption lines are revealed in stacked spectra from cross-correlating the... -
Photometry and spectroscopy of IRAS 18111-2257
We present the discovery and multiwavelength characterization of SRGA-J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey.... -
AFGL 2591 and AFGL 2136 v=1-0 and v=2-1 transition
We have performed a high-resolution 4-13{mu}m spectral survey of the hot molecular gas associated with the massive protostars AFGL-2591 and AFGL-2136. Here we present the... -
^13^CO line in massive binary W3 IRS 5
We present in this paper the results of high spectral resolution (R=88100) spectroscopy at 4.7{mu}m with iSHELL/IRTF of hot molecular gas close to the massive binary protostar... -
LAT Gamma-ray spectra of RS Oph 2021 nova
We report the Fermi LAT {gamma}-ray detection of the 2021 outburst of the symbiotic recurrent nova RS Ophiuchi. In this system, unlike classical novae from cataclysmic binaries,... -
SED, optical & gamma-ray parameters for 656 blazars
It is known that the blazar jet emissions are dominated by nonthermal radiation, while the accretion disk jets are normally dominated by thermal emission. In this work,... -
LAMOST parameters for 188 white dwarfs
We present the first results from our ongoing project to study extremely low-mass (ELM) white dwarfs (WDs) (M<~0.3M{sun}) with the Large Sky Area Multi-Object Fiber... -
LEGA-C parameters for 877 galaxies
Dynamical models for 673 galaxies at z=0.6-1.0 with spatially resolved (long-slit) stellar kinematic data from LEGA-C are used to calibrate virial mass estimates defined as... -
Spectroscopy and photometry follow up for NGC 4151
Changing-look active galactic nucleus NGC4151, which has attracted a lot of attention, is undergoing the second dramatic outburst stage in its evolutionary history. To... -
B-type stars abundances from LAMOST DR5 LRS sp.
We present detailed criteria for the classification of subtypes of B-type supergiants and apply them to 97 supergiants chosen manually from the LAMOST DR5 data set. We obtained... -
Chandra obs. of the Trifid region & ARCoIRIS sp.
The dynamical states of molecular clouds may affect the properties of the stars they form. In the vicinity of the Trifid Nebula (d=1180+/-25pc), the main star cluster (Trifid... -
Superwinds. III. Non-equilibrium Photoionization
Observations of some starburst-driven galactic superwinds suggest that strong radiative cooling could play a key role in the nature of feedback and the formation of stars and... -
Low-mass active galaxies from GAMA DR4
We present an entirely new sample of 388 low-mass galaxies (M_<=10^10^M{sun}) that have spectroscopic signatures indicating the presence of massive black holes (BHs) in the... -
Characterizing extreme em. line gal. II. COS & LBT
Observations of high-redshift galaxies (z>5) have shown that these galaxies have extreme emission lines with equivalent widths much larger than their local star-forming...
