JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST...

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...

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...

Detecting the presence and characteristic scale of a signal is a common problem in data analysis. We develop a fast statistical test of the null hypothesis that a Fourier-like...

We present medium-resolution K-band long-slit spectroscopy of 29 true, likely, possible, and candidate Galactic Plane planetary nebulae (PNe) from the UWISH2 survey, many of...

We provide a comprehensive census of the near-infrared (NIR, 0.8-2.4um) spectroscopic properties of 102 nearby (z<0.075) active galactic nuclei (AGN), selected in the hard...

A computed line list for formaldehyde, H_2_^12^C^16^O, applicable to temperatures up to T=1500K is presented. An empirical potential energy and ab initio dipole moment surfaces...

Knowledge of the elemental abundances of symbiotic giants is essential to address the role of chemical composition in the evolution of symbiotic binaries, to map their parent...

A comprehensive hot line list is calculated for ^31^PH_3_ in its ground electronic state. This line list, called SAlTY, contains almost 16.8 billion transitions between 7.5...

Accurate rotation-vibration line lists are calculated for silicon monoxide. Line lists are presented for the main isotopologue, ^28^Si^16^O, and four monosubstituted...

Accurate line lists for three molecules, BeH, MgH and CaH, in their ground electronic states are presented. These line lists are suitable for temperatures relevant to...

We present a library of 139 near-IR spectra of cool asymptotic giant branch stars that will be useful for comparison with theoretical model atmosphere calculations and for...

Using Spitzer-infrared spectrograph (IRS) spectroscopy, we investigate the ubiquity of active galactic nuclei (AGN) in a complete (~94%), volume-limited sample of the most...

Nitride dust is predicted to form in small amounts around carbon stars, but the most likely candidate species such as aluminium nitride (AlN) have not yet been detected....

We present four epochs, A, B, C and D, of resolution ({lambda}/{delta}{lambda}) = 1200, 2.12 micron spectroscopy of the peculiar X-ray binary Cygnus X-3. About a half dozen...

Laboratory spectra through the mid-infrared (4000 to 500cm^-1^ [2.5-20 micron]) have been used to calculate the optical constants (n and k) and integrated absorption...

We present precise measurements of radial (RV) and projected rotational (vsini) velocities of a sample of 258 M6 to L2 dwarfs with multiepoch, high-resolution...

The Tarantula Nebula (30 Doradus, 30 Dor) is the most important star-forming complex in the Local Group, offering a microscope on starburst astrophysics. At its heart lies the...

We present a sample of 305 QSO candidates having |b|<30{deg}, the majority with GALEX magnitudes near-UV<18.75. To generate this sample, we apply UV-IR color selection...

We have established and released a new stellar index library of the CaII triplet, which serves as an indicator for characterizing the chromospheric activity of stars. The...
