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…
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…
A physical model for [CII] line emission from galaxies
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…
Dynamical Properties of Molecular-forming Gas Clumps in Galaxies at the Epoch of Reionization
T. K. Daisy Leung, Andrea Pallottini, Andrea Ferrara +1
We study the properties of molecular-forming gas clumps (MGCs) at the epoch of reionization using cosmological zoom-in simulations. We identify MGCs in a z=6 prototypical galaxy ("…
Kinematics of galaxies from [CII] line emission
M. Kohandel, A. Pallottini, A. Ferrara +5
We study the kinematical properties of galaxies in the Epoch of Reionization via the [CII] 158m line emission. The line profile provides information on the kinematics as well as…
Deep into the structure of the first galaxies: SERRA views
A. Pallottini, A. Ferrara, D Decataldo +6
We study the formation and evolution of a sample of Lyman Break Galaxies in the Epoch of Reionization by using high-resolution (), cosmological zoom-in simulati…
Photoevaporation of Jeans-unstable molecular clumps
D. Decataldo, A. Pallottini, A. Ferrara +2
We study the photoevaporation of Jeans-unstable molecular clumps by isotropic FUV (6 eV < 13.6 eV) radiation, through 3D radiative transfer hydrodynamical simulations…
Lyα emission from galaxies in the Epoch of Reionization
Christoph Behrens, Andrea Pallottini, Andrea Ferrara +2
The intrinsic strength of the Ly line in young, star-forming systems makes it a special tool for studying high-redshift galaxies. However, interpreting observations remains chal…
First Identification of 10-kpc Scale [CII] 158um Halos around Star-Forming Galaxies at z=5-7
Seiji Fujimoto, Masami Ouchi, Andrea Ferrara +7
We report the discovery of 10-kpc scale [CII] 158um halos surrounding star-forming galaxies in the early Universe. We choose deep ALMA data of 18 galaxies each with a star-formatio…
Constraints on high-J CO emission lines in quasars
S. Carniani, S. Gallerani, L. Vallini +10
We present Atacama Large Millimiter/submillimiter Array (ALMA) observations of eight highly excited CO (J) lines and continuum emission in two quasars: SDSS J…
