The periphery of the Small Magellanic Cloud (SMC) can unlock important information regarding galaxy formation and evolution in interacting systems. Here, we...
sMILES SSPs: a library of semi-empirical MILES stellar population models with variable [α/Fe] abundances
We present a new library of semi-empirical stellar population models that are based on the empirical MILES and semi-empirical sMILES stellar libraries. The...
Smooth kinematic and metallicity gradients reveal that the Milky Way's nuclear star cluster and disc might be part of the same structure
Context. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters. Nevertheless, these clusters are not...
SNhunt151: an explosive event inside a dense cocoon
SNhunt151 was initially classified as a supernova (SN) impostor (nonterminal outburst of a massive star). It exhibited a slow increase in luminosity, lasting...
SOFIA/FORCAST resolves 30-40 μm extended dust emission in nearby active galactic nuclei
We present arcsecond-scale observations of the active galactic nuclei (AGNs) of seven nearby Seyfert galaxies observed from the Stratospheric Observatory For...
SOFIA/HAWC+ Detection of a Gravitationally Lensed Starburst Galaxy at z = 1.03
We present the detection at 89 μm (observed frame) of the Herschel-selected gravitationally lensed starburst galaxy HATLAS J1429-0028 (also known as G15v2.19)...
Soft X-ray to far infrared luminosities ratio in star-forming galaxies: predictions from synthesis models
Context: A good correlation has been found in star-forming galaxies, between the soft X-ray and the far infrared or radio luminosities. The soft X-ray emission...
Solo dwarfs - III. Exploring the orbital origins of isolated Local Group galaxies with Gaia Data Release 2
We measure systemic proper motions for distant dwarf galaxies in the Local Group and investigate if these isolated galaxies have ever had an interaction with...
Solo dwarfs I: survey introduction and first results for the Sagittarius dwarf irregular galaxy
We introduce the Solitary Local dwarfs survey (Solo), a wide-field photometric study targeting every isolated dwarf galaxy within 3 Mpc of the Milky Way. Solo...
