MIDIS: Strong H $β$ +[OIII] Line Emitters at $z \geq 9$

Thomas R. Greve, Steven Gillman, Pierluigi Rinaldi +24

We present a search for strong H $β$ +[O III] emitters at $z = 9.4 - 11.3$ in the HUDF using ultra-deep JWST/MIRI F560W imaging from the MIDIS survey. Three galaxies are identified via p…

JWST Reveals Two Overmassive Black Hole Candidates in Dwarf Galaxies at z $\approx$ 0.7: Pushing Black Hole Searches into the Dwarf-Galaxy Regime

E. Iani, P. Rinaldi, A. Torralba +35

We report the discovery and characterization of two compact galaxies, Pelias and Neleus, at z ~ 0.71 and z ~ 0.75, identified in MACS J0416.1-2403 and GOODS-North. Both exhibit unu…

MIDIS: The identification of deep MIRI-red sources as candidates for extreme Balmer-break and line emitting galaxies at high-z

I. Jermann, G. Brammer, S. Gillman +27

We investigate the detection and nature of 5.6~μm MIRI-red sources in the MIRI Deep Imaging Survey (MIDIS), covering 2.4~arcmin $^{2}$ in the Hubble Ultra Deep Field. MIDIS is the dee…
