PHANGS-JWST First Results: A Global and Moderately Resolved View of Mid-Infrared and CO Line Emission from Galaxies at the Start of the JWST Era
Adam K. Leroy, Alberto D. Bolatto, Karin Sandstrom +41
We explore the relationship between mid-infrared (mid-IR) and CO rotational line emission from massive star-forming galaxies, which is one of the tightest scalings in the local uni…
Empirically-Driven Multiwavelength K-corrections At Low Redshift
Catherine E. Fielder, Brett H. Andrews, Jeffrey A. Newman +1
K-corrections, conversions between flux in observed bands to flux in rest-frame bands, are critical for comparing galaxies at various redshifts. These corrections often rely on fit…
A New Physical Picture for AGNs Lacking Optical Emission Lines
Christopher J. Agostino, Samir Salim, Sara L. Ellison +2
In this work, we use ~500 low-redshift (z ~ 0.1) X-ray AGNs observed by XMM-Newton and SDSS to investigate the prevalence and nature of AGNs that apparently lack optical emission l…
SIT 45: An interacting, compact, and star-forming isolated galaxy triplet
D. Grajales-Medina, M. Argudo-Fernández, P. Vásquez-Bustos +7
The merging system SIT 45 (UGC 12589) is an unusual isolated galaxy triplet, consisting of three merging late-type galaxies, out of 315 systems in the SIT (SDSS-based catalogue of…
SFR estimations from z=0 to z=0.9 -- A comparison of SFR calibrators for star-forming galaxies
M. Figueira, A. Pollo, K. Małek +7
Using VIPERS, we estimated a set of SFR based on photometric and spectroscopic data. We used, as estimators, photometric bands from ultraviolet to mid-infrared, and spectral lines.…
The fundamental metallicity relation from SDSS (z~0) to VIPERS (z~0.7) Data selection or evolution
F. Pistis, A. Pollo, M. Scodeggio +6
Aims. We focus on how to homogenize the comparison between galaxy samples having different characteristics. We check the projections of the fundamental metallicity relation (FMR) a…
