Near-Infrared Spectra of IC5117
Infrared spectroscopy from 0.8 to 2.5{mu}m is presented for the planetary nebula IC5117. The emission lines of IC5117 span a wide range of ionization that includes He II, [S... -
Binarity in planetary nebula central stars
We still do not know what causes aspherical planetary nebula (PN) morphologies. A plausible hypothesis is that they are due to the presence of a close stellar or substellar... -
TIMER catalogue of HII regions
In this study we perform a comparative analysis of the properties of the HII regions located in different areas of barred galaxies, with the aim of investigating the impact of... -
Filaments of Cygnus X
Filamentary gas structures are widely observed in molecular clouds, and are suggested to play a key role in the star formation processes. However, existing observations of... -
Precise determination of disk lifetimes
Determining how long circumstellar disks last is key to understanding the timescale of planet formation. Typically, this is done by measuring the fraction of young stars with... -
Taurus Catalog
The Spitzer Space Telescope Survey of the Taurus is a Legacy III project titled, Taurus 2: Finishing the Spitzer Map of the Taurus Molecular Clouds (Taurus). The Taurus Spitzer... -
Simultaneous SiO and H2O maser observations. IV.
Based on the simultaneous observational results of SiO and H_2_O masers toward 401 evolved stars, we have performed statistical analyses. We find that the peak and integrated... -
Metallicity maps diagnostic in AMUSING++ galaxies
We analyse the spatial statistics of the 2D gas-phase oxygen abundance distributions in a sample of 219 local galaxies. We introduce a new adaptive binning technique to enhance... -
LOFAR Two-metre Sky Survey (LoTSS) DR3
We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12950 hrs of data (18.6... -
12CO gas structures of protoplanetary disks
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA ^12^CO spectral line visibilities. We derived gas-disk radii, integrated... -
Auriga-California Molecular Cloud
The Auriga-California molecular cloud is a large region of relatively modest star formation that is part of the Gould Belt. The Herschel Space Observatory program... -
HI composite survey survey collection
Composite all-sky map of neutral hydrogen column density (N_HI), formed from the Leiden/Dwingeloo HI survey data (Hartmann & Burton 1997) and the composite N_HI map of... -
Dame and Thaddeus 2022 Velocity Integrated CO Map survey collection
Data published by Dame & Thaddeus (2022) significantly extends the Galactic plane CO survey of Dame, Hartmann & Thaddeus (2001) with complementary coverage of the entire... -
PlanckRevised CO21 survey collection
The Planck space mission has observed the first three rotational lines of emission of Galactic carbon monoxide (CO). Those maps, however, are either noisy or contaminated by... -
CO composite survey survey collection
This survey contains data from the composite CO map constructed by Dame, Hartmann and Thaddeus (2001) from 37 individual surveys of the Galaxy in the CO (1-0) line. Due to the... -
A Database of Circumstellar OH Masers: Interferometric Followups
A all-sky compilation of galactic stellar sources observed for OH maser emission in the transitions at 1612, 1665, and 1667 MHz. The database contains OH maser observations... -
A Database of Circumstellar OH Masers: Monitoring Programs
A all-sky compilation of galactic stellar sources observed for OH maser emission in the transitions at 1612, 1665, and 1667 MHz. The database contains OH maser observations... -
Reference HII Regions for Abundance Determination (SCS)
A table containing reference data for HII regions. We also give a source code to compute abundances and electron temperatures in HII regions from strong emission lines. -
Magellanic Clouds Extinction Values
A catalogue of E(V-I) extinction values is presented for 3174 (LMC) and 693 (SMC) fields within the Magellanic Clouds. The extinction values were computed by determining the... -
Northern Sky Narrowband Survey: Continuum HIPS
The Northern Sky Narrowband Survey maps the entire northern hemisphere down to a declination of -16° in the light of the emission lines H-alpha (656.3 nm), [OIII] (500.7 nm) and...
