In this second paper in a series of papers based on the most-up-to-date catalogue of symbiotic stars (SySts), we present a new approach for identifying and distinguishing SySts...

We present the best 265 sampled R-band light curves of spectroscopically identified Type Ia supernovae (SNe) from the Palomar Transient Factory (PTF; 2009-2012) survey and the...

We study the accuracy of spectroscopic radial velocities (RVs) by comparing spectroscopic and astrometric RVs for stars of the Hyades open cluster. We obtained High-Accuracy...

We present a study of the integrated properties of the 835 galaxies in the Calar-Alto Legacy Integral Field spectroscopy Area survey. To derive the main physical parameters of...

We present the results of a search for galaxy clusters and groups in the ~2deg^2^ of the COSMOS field using all available X-ray observations from the XMM-Newton and Chandra...

The Herschel Space telescope carried out an unprecedented survey of nearby stars for debris discs. The dust present in these debris discs scatters and polarizes stellar light in...

Swan bands - characteristic molecular absorption features of the C2 molecule - are a spectroscopic signature of carbon-enhanced stars. They can also be used to identify...

We present the results from NH_3_ mapping observations towards 34 regions identified by the Red MSX Source (RMS) survey. We have used the Australia Telescope Compact Array to...

Using stellar population models, we predicted that the Dark Energy Survey (DES) - due to its special combination of area (5000deg^2^) and depth (i=24.3) - would be in the...

We assemble the largest sample of oxygen-rich (O-rich) Miras and associated long-period variables (LPVs) to date and highlight their importance for age dating the components of...

We create and analyse the largest up-to-date all-sky compilation of the interstellar optical polarization data supplemented by the reddening data This compilation includes 13...

We present new Hubble Space Telescope (HST) ultraviolet and ground-based optical observations of the hot, metal-rich white dwarf GD 394. Extreme-ultraviolet (EUV) observations...

We present the colour and flux variability analysis at 3.4{mu}m (W1 band) and 4.6{mu}m (W2 band) of 492 narrow-line Seyfert 1 (NLSy1) galaxies using archival data from the...

We describe the Sloan Digital Sky Survey IV (SDSS-IV) MaNGA (Mapping Nearby Galaxies at Apache Point Observatory) PyMorph Photometric (MPP-VAC) and MaNGA Deep Learning...

We study the morphological and structural properties of the host galaxies associated with 57 optically selected luminous type 2 active galactic nuclei (AGNs) at z~0.3-0.4: 16...

We present a catalogue of an HI-selected sample of 1129 low surface brightness galaxies (LSBGs) searched from the {alpha}.40-SDSS DR7 survey. This sample, consisting of various...

Using the Mopra telescope, we have targeted 61 regions in the Carina Nebula, covering an area of 1.5deg^2^, of bright and compact 870{mu}m dust continuum emission for molecular...

Around 10 per cent of bright low-frequency radio sources observed with the Murchison Wide-field Array (MWA) show strong interplanetary scintillation (IPS) on time-scales of a...

Rotation periods from Kepler K2 are combined with projected rotation velocities from the WIYN 3.5m telescope to determine projected radii for fast-rotating, low-mass...

We present the discovery of a 3h5m orbital-period binary star at the heart of the planetary nebula M 3-1 - the shortest period photometrically variable central star known and...
