Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei
Francesco Shankar, David H. Weinberg, Christopher Marsden +25
The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…

Hyewon Suh, Francesca Civano, Benny Trakhtenbrot +4
We investigate the cosmic evolution of the ratio between black hole mass (MBH) and host galaxy total stellar mass (Mstellar) out to z~2.5 for a sample of 100 X-ray-selected moderat…

We report the discovery of a high-redshift, massive molecular outflow in the starburst galaxy SPT0346-52 () via the detected absorption of high-excitation water transition…
Supernovae within Pre-existing Wind-Blown Bubbles: Dust Injection vs. Ambient Dust Destruction
Sergio Martínez-González, Richard Wünsch, Sergiy Silich +3
By means of 3-D hydrodynamical simulations, here we evaluate the impact that supernova explosions occurring within wind-driven bubbles have on the survival or destruction of dust g…
Impact of AGN feedback on galaxies and their multiphase ISM across cosmic time
Milena Valentini, Giuseppe Murante, Stefano Borgani +6
We present simulations of galaxy formation, based on the GADGET-3 code, in which a sub-resolution model for star formation and stellar feedback is interfaced with a new model for A…
The 3D structure of CO depletion in high-mass prestellar regions
S. Bovino, S. Ferrada-Chamorro, A. Lupi +3
Disentangling the different stages of the star-formation process, in particular in the high-mass regime, is a challenge in astrophysics. Chemical clocks could help alleviating this…
Studying high-z galaxies with [CII] intensity mapping
Bin Yue, Andrea Ferrara
We investigate the [CII] line intensity mapping (IM) signal from galaxies in the Epoch of Reionization (EoR) to assess its detectability, the possibility to constrain the $L_{\rm C…
Constraining black hole-galaxy scaling relations from the large-scale clustering of Active Galactic Nuclei and implied mean radiative efficiency
Francesco Shankar, Viola Allevato, Mariangela Bernardi +11
A supermassive black hole has been found at the centre of nearly every galaxy observed with sufficient sensitivity. The masses of these black holes are observed to increase with ei…
The Chandra COSMOS Legacy Survey: clustering dependence of Type 2 AGN on host galaxy properties
V. Allevato, A. Viitanen, A. Finoguenov +10
Aims. We perform clustering measurements of 800 X-ray selected Chandra COSMOS Legacy (CCL) Type 2 AGN with known spectroscopic redshift to probe the halo mass dependence on AGN hos…
Impact of X-rays on CO emission from high-z galaxies
L. Vallini, A. G. G. M. Tielens, A. Pallottini +5
We study the impact of active galactic nuclei (AGN) on the CO Spectral Line Energy Distribution (SLED) of high- galaxies. In particular, we want to assess if the CO SLED can be…
Detecting the halo heating from AGN feedback with ALMA
Simcha Brownson, Roberto Maiolino, Marco Tazzari +2
The Sunyaev-Zel'dovich (SZ) effect can potentially be used to investigate the heating of the circumgalactic medium and subsequent suppression of cold gas accretion onto the host ga…
Large Population of ALMA Galaxies at z>6 with Very High [OIII]88um to [CII]158um Flux Ratios: Evidence of Extremely High Ionization Parameter or PDR Deficit?
Yuichi Harikane, Masami Ouchi, Akio K. Inoue +20
We present our new ALMA observations targeting [OIII]88um, [CII]158um, [NII]122um, and dust continuum emission for three Lyman break galaxies at z=6.0293-6.2037 identified in the S…
Dark-ages reionization and galaxy formation simulation -- XVIII. The high-redshift evolution of black holes and their host galaxies
Madeline A. Marshall, Simon J. Mutch, Yuxiang Qin +2
Correlations between black holes and their host galaxies provide insight into what drives black hole-host co-evolution. We use the Meraxes semi-analytic model to investigate the gr…

A. Ferrara, L. Vallini, A. Pallottini +5
A tight relation between the [CII]158m line luminosity and star formation rate is measured in local galaxies. At high redshift (), though, a much larger scatter is observed…
