Kiloparsec-scale gaseous clumps and star formation at
S. Carniani, R. Maiolino, R. Amorin +13
We investigate the morphology of the [CII] emission in a sample of "normal" star-forming galaxies at in relation to their UV (rest-frame) counterpart. We use new ALMA obs…
Galaxy evolution studies with the SPace IR telescope for Cosmology and Astrophysics (SPICA): the power of IR spectroscopy
L. Spinoglio, A. Alonso-Herrero, L. Armus +65
IR spectroscopy in the range 12-230 micron with the SPace IR telescope for Cosmology and Astrophysics (SPICA) will reveal the physical processes that govern the formation and evolu…
CO line emission from galaxies in the Epoch of Reionization
L. Vallini, A. Pallottini, A. Ferrara +3
We study the CO line luminosity (), the shape of the CO Spectral Line Energy Distribution (SLED), and the value of the CO-to- conversion factor in galaxies in…
ALMA reveals metals yet no dust within multiple components in CR7
J. Matthee, D. Sobral, F. Boone +8
We present spectroscopic follow-up observations of CR7 with ALMA, targeted at constraining the infrared (IR) continuum and [CII] line-emission at high spatial resolu…
Molecular clumps photoevaporation in ionized regions
Davide Decataldo, Andrea Ferrara, Andrea Pallottini +2
We study the photoevaporation of molecular clumps exposed to a UV radiation field including hydrogen-ionizing photons ( eV) produced by massive stars or quasars. We follo…
The impact of chemistry on the structure of high-z galaxies
A. Pallottini, A. Ferrara, S. Bovino +4
To improve our understanding of high-z galaxies we study the impact of H chemistry on their evolution, morphology and observed properties. We compare two zoom-in high-resolut…
Quasar outflows at : the impact on the host galaxies
Paramita Barai, Simona Gallerani, Andrea Pallottini +5
We investigate quasar outflows at by performing zoom-in cosmological hydrodynamical simulations. By employing the SPH code GADGET-3, we zoom in the region ar…
X-ray spectroscopy of the z=6.4 quasar J1148+5251
Simona Gallerani, Luca Zappacosta, Maria Carmela Orofino +9
We present the 78-ks Chandra observations of the quasar SDSS J1148+5251. The source is clearly detected in the energy range 0.3-7 keV with 42 counts (with a significance $\…
The nature of the Lyman Alpha Emitter CR7: a persisting puzzle
Fabio Pacucci, Andrea Pallottini, Andrea Ferrara +1
The peculiar emission properties of the Ly emitter CR7 have been initially interpreted with the presence of either a direct collapse black hole (DCBH) or a substant…
High Mass X-ray Binaries and the Cosmic 21-cm Signal: Impact of Host Galaxy Absorption
Arpan Das, Andrei Mesinger, Andrea Pallottini +2
By heating the intergalactic medium (IGM) before reionization, X-rays are expected to play a prominent role in the early Universe. The cosmic 21-cm signal from this "Epoch of Heati…
Extended ionised and clumpy gas in a normal galaxy at z=7.1 revealed by ALMA
S. Carniani, R. Maiolino, A. Pallottini +10
We present new ALMA observations of the [OIII]88m line and high angular resolution observations of the [CII]158m line in a normal star forming galaxy at z7.1. Previous [CI…
