MICONIC: Dual active galactic nuclei, star formation, and ionised gas outflows in NGC 6240 seen with MIRI/JWST

L. Hermosa Muñoz, A. Alonso-Herrero, A. Labiano +19

As part of the guaranteed time observations program Mid-Infrared Characterization Of Nearby Iconic galaxy Centers (MICONIC), we used the medium-resolution spectrometer (MRS) of the…

Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions

A. Andrews, J. Jasche, G. Lavaux +147

A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…

Combined analysis of the 12.8 and 15 JWST/MIRI eclipse observations of TRAPPIST-1 b

Elsa Ducrot, Pierre-Olivier Lagage, Michiel Min +36

The first JWST/MIRI photometric observations of TRAPPIST-1 b allowed for the detection of the thermal emission of the planet at 15 , suggesting that the planet could be a bare…

Radio Galaxies in SIMBA: A MIGHTEE Comparison

Nicole L. Thomas, Imogen H. Whittam, Catherine L. Hale +4

We present a qualitative comparison between the host and black hole properties of radio galaxies in the MeerKAT GigaHertz Tiered Extragalactic Exploration~(MIGHTEE) survey with the…

Behind the dust veil: A panchromatic view of an optically dark galaxy at z=4.82

Nikolaj B. Sillassen, Shuowen Jin, Georgios E. Magdis +30

Optically dark dusty star-forming galaxies (DSFGs) play an essential role in massive galaxy formation at early cosmic time, however their nature remains elusive. Here we present a…

New Ionization Models and the Shocking Nitrogen Excess at z > 5

Sophia R. Flury, Karla Z. Arellano-Córdova, Edward C. Moran +1

The new era of galaxy evolution studies hearkened in by JWST has led to the discovery of z > 5 galaxies exhibiting excess nitrogen with log(N/O)~1 dex or more than expected from lo…
