Insight into the Starburst Nature of Galaxy GN-z11 with JWST MIRI Spectroscopy

J. Álvarez-Márquez, A. Crespo Gómez, L. Colina +21

This paper presents a deep MIRI/JWST medium resolution spectroscopy (MRS) covering the rest-frame optical spectrum of the GN-z11 galaxy. The [OIII]5008 and H emission lines are…

Water depletion and 15NH3 in the atmosphere of the coldest brown dwarf observed with JWST/MIRI

H. Kühnle, P. Patapis, P. Mollière +21

With a temperature of K WISE0855 is the coldest brown dwarf observed so far. Using the James Webb Space Telescope (JWST) we obtained observations that allow us to charac…

JWST Observations of Young protoStars (JOYS). Overview of gaseous molecular emission and absorption in low-mass protostars

M. L. van Gelder, L. Francis, E. F. van Dishoeck +17

The MIRI-MRS instrument onboard JWST allows for probing the molecular gas composition at mid-IR wavelengths at unprecedented resolution and sensitivity. It is important to study th…
