Measuring patchy reionisation with kSZ-21 cm correlations

Q. Ma, K. Helgason, E. Komatsu +2

We study cross-correlations of the kinetic Sunyaev-Zel'dovich effect (kSZ) and 21 cm signals during the epoch of reionisation (EoR) to measure the effects of patchy reionisation. S…

The THESEUS space mission concept: science case, design and expected performances

L. Amati, P. O'Brien, D. Goetz +208

THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-…

Metal enrichment signatures of the first stars on high-z DLAs

Q. Ma, U. Maio, B. Ciardi +1

We use numerical N-body hydrodynamical simulations with varying PopIII stellar models to investigate the possibility of detecting first star signatures with observations of high-re…

Distortions of the Cosmic Microwave Background through cooling lines during the epoch of Reionization

Carlos Hernandez-Monteagudo, Umberto Maio, Benedetta Ciardi +1

By using N-body hydrodynamical cosmological simulations in which the chemistry of major metals and molecules is consistently solved for, we study the interaction of metallic fine-s…

Constraining the contribution of active galactic nuclei to reionisation

Sultan Hassan, Romeel Davé, Sourav Mitra +3

Recent results have suggested that active galactic nuclei (AGN) could provide enough photons to reionise the Universe. We assess the viability of this scenario using a semi-numeric…

Do Cosmic Rays Heat the Early Intergalactic Medium?

Natacha Leite, Carmelo Evoli, Marta D'Angelo +3

Cosmic rays (CRs) govern the energetics of present-day galaxies and might have also played a pivotal role during the Epoch of Reionization. In particular, energy deposition by low-…

Upper limits on the 21-cm Epoch of Reionization power spectrum from one night with LOFAR

A. H. Patil, S. Yatawatta, L. V. E. Koopmans +25

We present the first limits on the Epoch of Reionization (EoR) 21-cm HI power spectra, in the redshift range , using the Low-Frequency Array (LOFAR) High-Band Antenna (…

CMB-induced radio quenching of high-redshift jetted AGNs with highly magnetic hotspots

Jianfeng Wu, Gabriele Ghisellini, Edmund Hodges-Kluck +5

In an effort to understand the cause of the apparent depletion in the number density of radio-loud AGNs at , this work investigates the viability of the so-called Cosmic Micro…

Recovering the HII region size statistics from 21-cm tomography

Koki Kakiichi, Suman Majumdar, Garrelt Mellema +7

We introduce a novel technique, called "granulometry", to characterize and recover the mean size and the size distribution of HII regions from 21-cm tomography. The technique is ea…

Enabling Radiative Transfer on AMR grids in CRASH

N. Hariharan, L. Graziani, B. Ciardi +2

We introduce CRASH-AMR, a new version of the cosmological Radiative Transfer (RT) code CRASH, enabled to use refined grids. This new feature allows us to attain higher resolution i…
