The burgeoning rise of the 21-cm forest I: constraints on the optical depth of the intergalactic medium at
Chanasorn Kongprachaya, Gianni Bernardi, Emilio Ceccotti +3
The redshifted 21-cm line is a promising probe of the Epoch of Reionization, during which the first generation of stars ionized the InterGalactic Medium (IGM). We aimed to constrai…
Forest without Trees is still Fruitful: Constraints on the thermal state of the neutral IGM at with the 21-cm forest power spectrum
Tomáš Šoltinský, Arnab Chakraborty, Girish Kulkarni +10
Neutral regions of the intergalactic medium (IGM) during the Epoch of Reionization (EoR) remain largely unexplored due to the limitations of existing probes. Owing to discoveries o…
Overview of 21cm Experiments at high redshift with SKAO
CD Science Working Group, Gianni Bernardi, Daniela Breitman +81
We provide an overview of the eight SKAO Science Book chapters that motivate the Epoch of Reionisation and Cosmic Dawn experiments with SKA-Low. We describe the individual SKA-Low…
Exploring the Cosmic Dawn through the 21 cm Forest and High-redshift Radio Sources with the SKA
Junsong Cang, Benedetta Ciardi, Barun Maity +12
The 21~cm forest, seen as absorption features in the spectra of distant radio sources, is produced by intervening neutral hydrogen and offers a direct probe of the neutral intergal…
Stellar feedback SPICEs up [C II] emission in the first galaxies
Aniket Bhagwat, Tiago Costa, Benedetta Ciardi +1
The bright [C II] 158 micron line is widely used to trace star-forming gas and feedback-driven outflows in high-redshift galaxies. Using the SPICE simulations, we investigate how b…
New constraints on stellar feedback through [O III] emission: interpreting ALMA and JWST observations with SPICE simulations
Benedetta Casavecchia, Aniket Bhagwat, Benedetta Ciardi +2
ALMA and JWST have recently detected emission lines from the interstellar medium of star-forming galaxies during the Epoch of Reionization, reaching redshifts up to z = 14. Among t…
Pulsar scintillation studies with LOFAR III. Annual variations in PSR~J08147429
Yanqing Cai, Ziwei Wu, Weiwei Zhu +27
The interstellar scintillation observed in radio pulsars arises from interference between electromagnetic waves scattered by electron density fluctuations in the turbulent interste…
POLAR-II: modeling star formation history of galaxies on the 21-cm signal from Epoch of Reionization
Qing-Bo Ma, Raghunath Ghara, Benedetta Ciardi +6
Galaxies may suffer some starburst and quenched periods in their history due to e.g. galaxy mergers and feedback. However, semi-numerical simulations of the Epoch of Reionization (…
Probing the magnetic field of a coronal mass ejection with PSR J1022+1001
El Mehdi Zahraoui, Hannah T. Rüdisser, Golam M. Shaifullah +24
We investigate whether low-frequency pulsar observations can provide LoS magnetic field estimates and whether these are consistent with synthetic LoS signatures extracted from a th…
The Collective Voice of Ly Emitters: Insights from JWST Stacked Spectroscopy
R. Tripodi, L. Napolitano, L. Pentericci +20
We present a spatially resolved stacked analysis of 287 LAEs at observed with JWST/NIRSpec prism spectroscopy. By constructing a two-dimensional stack from public surveys (CA…
