Ram-pressure stripping caught in action in a young cluster at
Ke Xu, Tao Wang, Emanuele Daddi +16
Galaxy clusters in the local Universe are dominated by massive quiescent galaxies with old ages, formed at high redshifts. Whether their quenching is driven by internal processes o…
Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at
F. Gentile, E. Daddi, D. Elbaz +165
We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive () star-forming (SFR /…
Quiescent fractions in high-redshift galaxy groups reflect their hot-or-cold state of gas accretion
Guillaume Elias, Emanuele Daddi, Chiara D'Eugenio +15
Cold accretion and quenching are closely related aspects of galaxy evolution, as sustained gas supply is required to maintain star formation. High-redshift galaxy groups therefore…
Prevailing thermally-pulsing-asymptotic-giant branch stars in the near-infrared rest-frame spectra of distant quiescent galaxies: towards robust galaxy ages and masses
Shiying Lu, Emanuele Daddi, Claudia Maraston +13
We recently reported the discovery of prominent features from the thermally pulsing asymptotic-giant-branch (TP-AGB) phase in the rest-frame near-infrared of a massive quiescent ga…
A first [CII] view of high-z quiescent galaxies
C. D'Eugenio, E. Daddi, R. Gobat +10
We present ALMA detections (or stringent upper limits) of the [CII] 158 emission line and underlying dust continuum from five massive quenched galaxies (QGs) at 2<z<4.7. We f…
Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3
Antonello Calabrò, Laura Pentericci, Anna Feltre +35
Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…
