MAGAZ3NE: Confirming Dust Deficiency and Quiescent Nature of Ultramassive Galaxies at 3 < z < 4 with ALMA Observations

The Astrophysical Journal
A major challenge in identifying massive quiescent galaxies at z  > 3 is distinguishing truly passive systems from dust-obscured star-forming galaxies, as both populations exhibit similar red ultraviolet-to-near-infrared colors.

Normal Galaxies in the Infrared [PDF]

, 2007
This review addresses what can be learned from infrared observations about galaxies powered predominantly by star formation. Infrared techniques mostly probe the interstellar medium of galaxies, yielding physical and chemical information on the medium out of which stars form, which is in turn affected by those stars.

NIKA2 Cosmological Legacy Survey. First measurement of the confusion noise at the IRAM 30 m telescope

Astronomy & Astrophysics
The NIKA2 Cosmological Legacy Survey (N2CLS) is a large programme using the NIKA2 dual-band camera on the IRAM 30 m telescope. Its goal is to improve our understanding of the physics of distant Dusty Star Forming Galaxies (DSFGs) by carrying out deep ...

The First Exploration of the Correlations Between WISE 12 μm and CO Emission in Early-type Galaxies

The Astrophysical Journal
We present the analysis of a comprehensive sample of 352 early-type galaxies using public data, to investigate the correlations between CO luminosities and mid-infrared luminosities observed by Wide-field Infrared Survey Explorer.

The Araucaria Project: Precise distances to Local Group galaxies from near-infrared photometry of RR Lyrae stars

EPJ Web of Conferences, 2017
We present results of the Araucaria Project’s investigation of RR Lyrae stars as distance indicators in nearby galaxies. With an aid of near-infrared period-luminositymetallicity relations available in the literature we determined distance moduli to five

Near-infrared imaging of interacting galaxies

The Astrophysical Journal, 1990
Galaxy-galaxy interactions are known to cause dramatic changes in morphology and at the same time often induce large bursts of star formation activity. While optical images are sufficient to reveal the overall morphological peculiarities of these systems, they suffer from several problems, the greatest of which is obscuration by dust within the ...

Halfway to the Peak: The JWST MIRI 5.6 μm Number Counts and Source Population

The Astrophysical Journal
We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 μ m images with 5 σ depths of ≈0.1 μ Jy. We detect 2854 sources within our combined area of 18.4 arcmin ^2 .
