A hybrid JHKs - W1W2W3W4 high-spectral index ({alpha}) selection scheme was employed to identify (sub)clusters of class I/f candidate protostars (YSOs) in WISE observations (the...

The sensitivity of a search for sources of TeV neutrinos can be improved by grouping potential sources together into generic classes in a procedure that is known as source...

From the cross-correlation of the IRAS FSC catalog with the radio FIRST catalog, 230 infrared galaxies were selected having optical classifications and redshifts from SDSS and...

We describe the properties of the 3838 galaxies that were monitored for SNe events, including newly determined morphologies and their DENIS and POSS-II/UKST I, 2MASS and DENIS J...

The 2MFGC catalog we have used contains 18020 galaxies selected from among the extended objects in the 2MASS infrared sky survey as having apparent ratios of the axes...

The results of a spectral classification of 257 M stars observed in the Cepheus region are given. Their equatorial coordinates, photographic stellar magnitudes, and spectral...

The S254-258 star-forming complex is a place of massive star formation where five OB-stars have created HII regions, visible as optical nebulae, and disrupted the parental...

The dominant source of radio continuum emissions at low frequencies is synchrotron radiation, which originates from star-forming regions in disc galaxies and from powerful jets...

We present a near infrared spectroscopic atlas of nearby, bright early-type galaxies with radio emission, containing 163 galaxies observed by the Palomar 200" TripleSpec...

We report 18 dust continuum detections >=3.3{sigma} at ~88um and 158um out of 49 ultraviolet(UV)-bright galaxies M_UV_<-21.3mag at z>6.5, observed by the Cycle-7 ALMA...

The Milky Way nuclear star cluster (NSC) is located within the nuclear stellar disc (NSD) in the Galactic Centre. It is not fully understood if the formation and evolution of...

We present a study of the radio continuum properties of two luminous/ultraluminous infrared galaxy samples: the OH megamaser (OHM) sample (74 objects) and the control sample...

We present a near-infrared spectroscopic survey of narrow-line Seyfert 1 galaxies in the southern hemisphere (using the SOFI instrument on the ESO-NTT telescope), sampled from...

We present APEX-LABOCA 870-{mu}m observations of the fields surrounding the nine brightest high-redshift unlensed objects discovered in the South Pole Telescope's (SPT) 2500...

Current models predict that binary interactions are a major ingredient in the formation of bipolar planetary nebulae (PNe) and pre-planetary nebulae (PPNe). Despite years of...

Polycyclic aromatic hydrocarbons (PAHs) are of great astrochemical and astrobiological interest due to their potential to form prebiotic molecules. We analyse the 7.7 and...

Due to its proximity, the Orion star forming region is often used as a proxy to study processes related to star formation and to observe young stars in the environment they were...

The VISTA Variables in the Via Lactea (VVV) survey and its extension have been monitoring about 560 deg^2^ of sky centred on the Galactic bulge and inner disc for nearly a...

The Beijing-Arizona Sky Survey (BASS) Data Release 3 (DR3) catalogue was released in 2019, which contains the data from all BASS and the Mosaic z-band Legacy Survey (MzLS)...

We present the results of a near-infrared (NIR) monitoring program carried out between 1999 and 2005 to determine the variability properties of the `Arecibo sample of OH/IR...
