LIGO and Virgo third observing run with GRANDMA
We present the Global Rapid Advanced Network Devoted to the Multi-messenger Addicts (GRANDMA). The network consists of 21 telescopes with both photometric and spectroscopic... -
APOGEE southern GCs with the BACCHUS code
We investigate the Fe, C, N, O, Mg, Al, Si, K, Ca, Ce, and Nd abundances of 2283 red giant stars in 31 globular clusters from high-resolution spectra observed in both the... -
NGC752 abundances from IR spectra
We present a detailed near-infrared chemical abundance analysis of 10 red giant members of the Galactic open cluster NGC 752. High-resolution (R~45000) near-infrared spectral... -
Effects of metallicity on HMXB formation
The heating of the intergalactic medium in the early, metal-poor Universe may have been partly due to radiation from high-mass X-ray binaries (HMXBs). Previous investigations on... -
Sub-Chandrasekhar progenitors for Type Ia SNe
A non-local-thermodynamic-equilibrium level population model of the first and second ionization stages of iron, nickel, and cobalt is used to fit a sample of XShooter optical +... -
Galaxies and groups around the WFI 2033-4723 lens
Galaxies and galaxy groups located along the line of sight towards gravitationally lensed quasars produce high-order perturbations of the gravitational potential at the lens... -
VANDELS massive quiescent galaxies at 1.0<z<1.3
We present a Bayesian full-spectral-fitting analysis of 75 massive (M_>10^10.3^M{sun}) UVJ-selected galaxies at redshifts of 1.0<z<1.3, combining extremely deep... -
Star formation in Milky Way analogues
The Milky Way has been described as an anaemic spiral, but is its star formation rate (SFR) unusually low when compared to its peers? To answer this question, we define a sample... -
APOKASC Evolutionary state of red-giant stars
The internal working of low-mass stars is of great significance to both the study of stellar structure and the history of the Milky Way. Asteroseismology has the power to... -
A new sample of southern radio galaxies
In this study we define a new sample of distant powerful radio galaxies in order to study their host galaxy properties and provide targets for future observations of HI... -
Spectral energy distributions of AGNs
We present spectral energy distributions (SEDs) of 41 active galactic nuclei, derived from multiwavelength photometry and archival spectroscopy. All of the SEDs span at least... -
Clumps and satellites impact on galaxy mass
We investigate the contribution of clumps and satellites to the galaxy mass assembly. We analysed spatially resolved HubbleSpace Telescope observations (imaging and slitless... -
Calibration of distances with deep learning
Gaia measures the five astrometric parameters for stars in the Milky Way, but only four of them (positions and proper motion, but not distance) are well measured beyond a few... -
Spectroscopic dust reverberation in NGC 5548
We have recently initiated the first spectroscopic dust reverberation programme on active galactic nuclei in the near-infrared. Spectroscopy enables measurement of dust... -
No evidence for IMBHs in {omega} Cen/NGC6624
We compare the results of a large grid of N-body simulations with the surface brightness and velocity dispersion profiles of the globular clusters {omega} Cen and NGC 6624. Our... -
Gaia DR2 extremely low-mass WD candidates
Extremely low-mass white dwarf stars (ELMs) are M<0.3M_{sun} helium-core white dwarfs born either as a result of a common-envelope phase or after a stable Roche lobe overflow... -
Period-luminosity relation of red supergiants
We revisit the K-band period-luminosity (P-L) relations of Galactic red supergiants using Gaia Data Release 2 parallaxes and up to 70yr of photometry from AAVSO and ASAS... -
Runaway stellar groups in the Orion A cloud
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... -
Chemical compositions of Galactic bulge stars
This work explores the detailed chemistry of the Milky Way bulge using the HERMES spectrograph on the Anglo-Australian Telescope. Here, we present the abundance ratios of 13... -
New Galactic clusters in the VVVX disc area
The 'VISTA Variables in the Via Lactea eXtended (VVVX)' ESO Public Survey is a near-infrared photometric sky survey that covers nearly 1700deg^2^ towards the Galactic disc and...
