Clumpy star formation and an obscured nuclear starburst in the luminous dusty z=4 galaxy GN20 seen by MIRI/JWST

A. Bik, J. Álvarez-Márquez, L. Colina +28

Dusty star-forming galaxies emit most of their light at far-IR to mm wavelengths as their star formation is highly obscured. Far-IR and mm observations have revealed their dust, ne…

Finding the dispersing siblings of young open clusters. Dynamical traceback simulations using Gaia DR3

Eero Vaher, David Hobbs, Paul McMillan +1

Context. Stars tend to form in clusters, but many escape their birth clusters very early. Identifying the escaped members of clusters can inform us about the dissolution of star cl…

Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. XIII. Ultraviolet Time Lag of H Emission in Mrk 142

V. C. Khatu, S. C. Gallagher, K. Horne +17

We performed a rigorous reverberation-mapping analysis of the broad-line region (BLR) in a highly accreting () active galactic nucleus, Markarian 142 (…

Spatially-resolved H and ionizing photon production efficiency in the lensed galaxy MACS1149-JD1 at a redshift of 9.11

J. Álvarez-Márquez, L. Colina, A. Crespo Gómez +32

We present MIRI/JWST medium-resolution spectroscopy (MRS) and imaging (MIRIM) of the lensed galaxy MACS1149-JD1 at a redshift of =9.10920.0002 (Universe age about 530 Myr).…

The cosmic build-up of dust and metals. Accurate abundances from GRB-selected star-forming galaxies at

K. E. Heintz, A. De Cia, C. C. Thöne +38

The chemical enrichment of dust and metals in the interstellar medium (ISM) of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we stud…

The incidence of AGN in galaxies with different stellar population ages

Q. Ni, J. Aird, A. Merloni +4

It has been argued that recycled gas from stellar mass loss in galaxies might serve as an important fuelling source for black holes (BHs) in their centers. Utilizing spectroscopic…
