We report the detection of variable stars within a 11.5arcminx11.5arcmin region near the Galactic Centre that includes the Arches and Quintuplet clusters, as revealed by the...

We present a study using the second data release of the GALAH survey of stellar parameters and elemental abundances of 15 pairs of stars identified by Oh et al. They identified...

In this work, we investigate the reason behind the increased occurrence of S0 galaxies in high-density environments. Our sample comprises of ~2500 spiral and ~2000 S0 galaxies...

HI stacking has proven to be a highly effective tool to statistically analyse average HI properties for samples of galaxies which may or may not be directly detected. With the...

We present the catalogue and basic properties of sources in AS2UDS, an 870-{mu}m continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716...

Identifying active galactic nuclei (AGNs) through their X-ray emission is efficient, but necessarily biased against X-ray-faint objects. We aim to characterize this bias by...

This work extends previous kinematic studies of young stars in the head of the Orion A cloud (OMC-1/2/3/4/5). It is based on large samples of infrared, optical, and X-ray...

We have determined the rate of large accretion events in Class I and II young stellar objects (YSOs) by comparing the all-sky digitized photographic plate surveys provided by...

We present optical photometric, spectroscopic data for the stars in the high Galactic latitude molecular cloud MBM 110. For the complete membership selection of MBM 110, we also...

NGC 6402 is among the most massive globular clusters in the Galaxy, but little is known about its detailed chemical composition. Therefore, we obtained radial velocities and/or...

We present a list of 220 face-on, almost bulgeless galaxies assumed to be counterparts to the objects from the Reference Flat Galaxy Catalogue (RFGC). We selected the Sc-, Scd-,...

We present bolometric light curves constructed from multiwavelength photometry of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project and the CfA Supernova Group,...

In a shallow near-infrared survey of the dwarf irregular galaxy, NGC3109, near the periphery of the Local Group, we have found eight Mira variables, seven of which appear to be...

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 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...

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 first data release (DR1) of the UVES Spectral Quasar Absorption Database (SQUAD), comprising 467 fully reduced, continuum-fitted high-resolution quasar spectra...

We have conducted a photometric survey of the globular cluster NGC 6397 in a search for variable stars. We obtained ~11h of time-resolved photometric images with one European...

Thanks to the MUSE integral field spectrograph on board the Very Large Telescope (VLT), extragalactic distance measurements with the [OIII]{lambda}5007 planetary nebula...

The present work presents our efforts at identifying new mercury-manganese (HgMn/CP3) stars using spectra obtained with the Large Sky Area Multi-Object Fiber Spectroscopic...
