MIDIS: Unveiling the Role of Strong Ha-emitters during the Epoch of Reionization with JWST

P. Rinaldi, K. I. Caputi, E. Iani +40

By using the ultra-deep \textit{JWST}/MIRI image at 5.6 in the Hubble eXtreme Deep Field, we constrain the role of strong H-emitters (HAEs) during Cosmic Reionization at $z…

AGN STORM 2: V. Anomalous Behavior of the CIV Light Curve in Mrk 817

Y. Homayouni, Gerard A. Kriss, Gisella De Rosa +49

An intensive reverberation mapping campaign on the Seyfert 1 galaxy Mrk817 using the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope (HST) revealed significant vari…

First rest-frame infrared spectrum of a z>7 quasar: JWST/MRS observations of J1120+0641

Sarah E. I. Bosman, Javier Álvarez-Márquez, Luis Colina +29

We present a JWST/MRS spectrum of the quasar J1120+0641 at z=7.0848, the first spectroscopic observation of a reionisation-era quasar in the rest-frame infrared (m). In…

A complex dust morphology in the high-luminosity AGN Mrk 876

Hermine Landt, Jake A. J. Mitchell, Martin J. Ward +9

Recent models for the inner structure of active galactic nuclei (AGN) advocate the presence of a radiatively accelerated, dusty outflow launched from the outer regions of the accre…
