The authors present digital spectra of O to M stars, luminosity classes V, III, and Ib in the wavelength range 5750-8950{AA}, at 15.5{AA} resolution. The stars follow well...

The atlas represents a collection of spectra in the wavelength range 2.00 to 2.45 micrometers having a resolution of approximately 0.02 micrometers. The sample of 73 stars...

This catalog contains a collection of K-band spectra for 26 stars with near-solar abundances, ranging in spectral class from F8 to M7 and in luminosity from dwarfs to...

It remains difficult to interpret the near-IR emission of young stellar populations. One main reason is our incomplete understanding of the spectra of luminous red stars. This...

Libraries of stellar spectra are fundamental tools for the study of stellar populations and both empirical and synthetic libraries have been used for this purpose. In this...

I present an analysis of archival spectra of 200 sources toward the Orion Nebula Cluster (ONC) that were obtained with the Near-Infrared Spectrograph (NIRSpec) onboard the James...

We present a catalogue of dense cores and filaments in a 3.8{deg}*2.4{deg} field around the TMC1 region of the Taurus molecular cloud. The catalogue was created using...

Understanding the links between different phases of outflows from active galactic nuclei is a key goal in extragalactic astrophysics. Here, we compare [OIII] {lambda}{lambda}...

We present chemical composition and fundamental parameters (the effective temperature, surface gravity and radius) for four sharp-lined A-type stars gamma Gem (HD 41705),...

Our Milky Way provides a unique test case for galaxy evolution models because of our privileged position within the Milky Way's disc. This position also complicates comparisons...

Supernovae (SNe) dominate the energy and momentum budget of stellar feedback, but the efficiency with which they couple to the interstellar medium (ISM) depends strongly on how...

Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES) utilizes long-duration pure parallel visits (~> 3 orbits) of HST at high Galactic latitude...

We present here medium resolution ({lambda}/{Delta}{lambda}~1200) H- and K-band spectra of M-type dwarf stars covering the wavelength ranges 1.50-1.80{mu}m and 1.95-2.45{mu}m....

Utilizing several instruments on 4-8m telescopes, we have observed a large sample of objects in the mid-infrared (8-13{mu}m). These comprise a few evolved stars, multiple...

Verifying that sub-mm galaxies are gravitationally lensed requires time-expensive observations with oversubscribed high-resolution observatories. Here, we aim to strengthen the...

We present a large, homogeneous catalogue of molecular clouds within 4kpc from the Sun at low Galactic latitudes (|b|<10{deg}) with unprecedented accurate distance...

Multimessenger astronomy received a great boost following the discovery of kilonova (KN) AT2017gfo, the optical counterpart of the gravitational wave source GW170817 associated...

Despite recent progress in understanding Ly {alpha} emitters (LAEs), relatively little is known regarding their typical black hole activity across cosmic time. Here, we study...

We study the M-type asymptotic giant branch (AGB) population of the Large Magellanic Cloud (LMC) by characterizing the individual sources in terms of the main properties of the...

We obtain distances to 383 Galactic Wolf-Rayet (WR) stars from Gaia DR2 parallaxes and Bayesian methods, with a prior based on HII regions and dust extinction. Distances agree...
