Euclid: Discovery of 31 new quasars at

D. Yang, J. F. Hennawi, F. Guarneri +211

We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…

JWST observes the assembly of a massive galaxy at z~4

Aayush Saxena, Roderik A. Overzier, Catarina Aydar +18

We present JWST observations of the radio galaxy TGSSJ1530+1049, spectroscopically confirmed at . NIRCam images and NIRSpec/IFU spectroscopy (R=2700) show that TGSSJ1530+104…

Beneath the Surface: >85% of z>5.9 QSOs in Massive Host Galaxies are UV-Faint

R. J. Bouwens, E. Banados, R. Decarli +20

We use [CII] observations of a large QSO sample to segregate sources by host galaxy mass, aiming to identify those in the most massive hosts. [CII] luminosity, a known tracer of mo…

Kiloparsec-Scale Alignment of a Radio Jet with Cool Gas and Dust in a z~6 Quasar

Fabian Walter, Eduardo Banados, Chris Carilli +11

We present high-angular resolution (0.068", ~400pc) ALMA imaging of the [CII] line and dust continuum emission of PSO J352.4034-15.3373, a radio-loud quasar at z=5.83. The observat…

ALMA 360 pc high-frequency observations reveal warm dust in the center of a quasar

Romain A. Meyer, Fabian Walter, Fabio Di Mascia +3

The temperature of the cold dust in z>6 galaxies is a potential tracer of Active Galactic Nucleus (AGN) and stellar feedback, and is the dominant source of uncertainty in inferring…

The [NII] 205 m line emission from high-z SMGs and QSOs

Saimurali Kolupuri, Roberto Decarli, Roberto Neri +8

We present [NII] 205 m fine structure line observations of three submillimeter galaxies (SMGs) and three quasar host galaxies at 4z6 using the Institut de ra…
