An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: II. The nature of FIR-bright quasars

Evanthia Hatziminaoglou, Hugo Messias, Duncan Farrah +5

We investigate the star formation properties and ultraviolet (UV)/optical spectral characteristics of 142 far-infrared (FIR)-bright quasars at redshifts 1 < z < 4 to probe supermas…

Galaxy interactions in void substructures: Morphology and stellar populations of two triplets from CAVITY

G. M. Azevedo, A. L. Chies-Santos, R. Riffel +5

Context. Cosmic voids are underdense regions of the Universe that provide a unique environment to study galaxy evolution in relative isolation. Galaxy triplets in voids are rare sy…

The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk

Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12

A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…

An ALMA Band 7 survey of SDSS/Herschel quasars in Stripe 82: I. The properties of the 870 micron counterparts

E. Hatziminaoglou, H. Messias, R. Souza +6

(Abridged) Quasar studies with Herschel/SPIRE often report host luminosities ranging from 10^{12} to 10^{14} Lsun, suggestive of star formation rates (SFRs) of up to several thousa…

Probing the origins. I. Generalised Additive Model inference of birth radii for Milky Way stars in the solar vicinity

M. L. L. Dantas, R. Smiljanic, R. S. de Souza +2

We employ a Generalised Additive Model (GAM) to address the limitations inherent in radial metallicity gradients predicted by chemical evolution models, thereby facilitating the es…

A high pitch angle structure in the Sagittarius Arm

M. A. Kuhn, R. A. Benjamin, C. Zucker +6

Context: In spiral galaxies, star formation tends to trace features of the spiral pattern, including arms, spurs, feathers, and branches. However, in our own Milky Way, it has been…
