Probing Ultra-late Reionization: Direct Measurements of the Mean Free Path over
Yongda Zhu, George D. Becker, Holly M. Christenson +22
The mean free path of ionizing photons, , is a critical parameter for modeling the intergalactic medium (IGM) both during and after reionization. We present direct mea…
NGC 2992: The interplay between the multiphase disk, wind and radio bubbles
Maria Vittoria Zanchettin, Chiara Feruglio, Marcella Massardi +13
We present an analysis of the gas kinematics in NGC 2992, based on VLT/MUSE, ALMA and VLA data, aimed at characterising the disk, the wind and their interplay in the cold molecular…
Crossing the Rubicon of Reionization with z~5 QSOs
A. Grazian, K. Boutsia, E. Giallongo +12
One of the key open questions in Cosmology is the nature of the sources that completed the cosmological hydrogen Reionization at z~5.2. High-z primeval galaxies have been long cons…
Star formation efficiency and AGN feedback in narrow-line Seyfert 1 galaxies with fast X-ray nuclear winds
Quentin Salomé, Yair Krongold, Anna Lia Longinotti +7
We present the first systematic study of the molecular gas and star formation efficiency in a sample of ten narrow-line Seyfert 1 galaxies selected to have X-ray Ultra Fast Outflow…
New quasar proximity zone size measurements at using the enlarged XQR-30 sample
Sindhu Satyavolu, Anna-Christina Eilers, Girish Kulkarni +15
Proximity zones of high-redshift quasars are unique probes of their central supermassive black holes as well as the intergalactic medium in the last stages of reionization. We pres…
First constraints of dense molecular gas at z~7.5 from the quasar Pōniuā'ena
Chiara Feruglio, Umberto Maio, Roberta Tripodi +13
We report the detection of CO(6-5) and CO(7-6) and their underlying continua from the host galaxy of quasar J100758.264+211529.207 (Pōniuā'ena) at z=7.5419, obtained with the NOrth…
