CONCERTO: Extracting the power spectrum of the [C II ] emission line
M. Van Cuyck, N. Ponthieu, G. Lagache +21
CONCERTO is the first experiment to perform a [CII] line intensity mapping survey to target . Measuring the [CII] power spectrum allows us to study the role of dusty star-fo…
CONCERTO: Simulating the CO, [CII], and [CI] line emission of galaxies in a 117 field and the impact of field-to-field variance
A. Gkogkou, M. Béthermin, G. Lagache +29
In the submm regime, spectral line scans and line intensity mapping (LIM) are new promising probes for the cold gas content and star formation rate of galaxies across cosmic time.…
Long Dark Gaps in the Ly Forest at : Evidence of Ultra Late Reionization from XQR-30 Spectra
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +22
We present a new investigation of the intergalactic medium (IGM) near reionization using dark gaps in the Lyman- (Ly) forest. With its lower optical depth, Ly offers a pot…
Chasing the Tail of Cosmic Reionization with Dark Gap Statistics in the Ly Forest over
Yongda Zhu, George D. Becker, Sarah E. I. Bosman +14
We present a new investigation of the intergalactic medium (IGM) near the end of reionization using "dark gaps" in the Lyman-alpha (Ly) forest. Using spectra of 55 QSOs at $z_{\…
Hydrogen reionisation ends by : Lyman- optical depth measured by the XQR-30 sample
Sarah E. I. Bosman, Frederick B. Davies, George D. Becker +23
The presence of excess scatter in the Ly- forest at , together with the existence of sporadic extended opaque Gunn-Peterson troughs, has started to provide robust evi…
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…
Mapping metals at high redshift with far-infrared lines
A. Pallottini, S. Gallerani, A. Ferrara +4
Cosmic metal enrichment is one of the key physical processes regulating galaxy formation and the evolution of the intergalactic medium (IGM). However, determining the metal content…
Simulating cosmic metal enrichment by the first galaxies
A. Pallottini, A. Ferrara, S. Gallerani +2
We study cosmic metal enrichment via AMR hydrodynamical simulations in a (10 Mpc/h) volume following the Pop III-Pop II transition and for different Pop III IMFs. We have analy…
Simulating intergalactic quasar scintillation
A. Pallottini, A. Ferrara, C. Evoli
Intergalactic scintillation of distant quasars is sensitive to free electrons and therefore complements Ly absorption line experiments probing the neutral intergalactic medium (…
