PAHSPECS: Spatially Resolved PAH Spectroscopy at cosmic noon with JWST MIRI MRS
Fergus R. Donnan, Karin Sandstrom, Irene Shivaei +10
We present spatially resolved spectroscopy with JWST/MIRI MRS of a representative sample of normal star-forming galaxies at as part of the PAHSPECS program. To extract e…
PAHSPECS: Polycyclic aromatic hydrocarbon properties at cosmic noon with JWST/MIRI MRS
Cristina Maria Lofaro, Tanio DÃaz Santos, Irene Shivaei +13
Context. Cosmic noon (z ~ 1-3) marks the peak of the cosmic star-formation rate density, when dust-obscured star formation dominated galaxy growth. Mid-infrared spectroscopy probes…
The Multi-phase Biconical Outflow in the local IR-Luminous Merger IRASF01364-1042
Y. Song, V. U, J. Kader +37
We investigate the spatially-resolved ISM properties of the local (), IR-luminous (\,L), late-stage galaxy merger IRAS F01364-1042, comb…
Little Red Dots: One Photometric Tag Concealing Diverse Spectroscopic Flavors of Massive Star Formation and Black Hole Activity
Pablo G. Pérez-González, Guillermo Barro, Stefano Carniani +62
We compile JWST/NIRSpec prism and MIRI data for 249 Little Red Dots (LRDs) at 2.3<z<9.3, forming a representative spectroscopic subset of NIRCam-selected LRDs. We derive a median s…
Spatially Resolved Star Formation relations in local LIRGs along the complete merger sequence
M. Sánchez-GarcÃa, T. DÃaz-Santos, L. Barcos-Muñoz +25
We investigate the properties of the interstellar medium (ISM) at ~100 pc scales in a sample of 27 nearby luminous infrared galaxies (LIRGs) spanning the entire merger sequence. In…
A Spectroscopically Calibrated Prescription for Extracting PAH Flux from JWST MIRI Imaging
Grant P. Donnelly, Thomas S. -Y. Lai, Lee Armus +24
We introduce a prescription for estimating the flux of the 7.7 micron and 11.3 micron\ polycyclic aromatic hydrocarbon (PAH) features from broadband JWST/MIRI images. Probing PAH f…
