Semi-analytical approach to Ly multiple-scattering in 21-cm signal simulations
Jordan Flitter, Julian B. Muñoz, Andrei Mesinger
A crucial physical quantity in determining the 21-cm signal during cosmic dawn is the inhomogeneous background of Ly photons originating from the first galaxies. As these photon…
Does it matter? A more careful treatment of density fluctuations in 21-cm simulations
Jordan Flitter, Sarah Libanore, Ely D. Kovetz
The cosmological 21-cm signal is sourced from hyperfine transitions in neutral hydrogen atoms. Yet, although the abundance of hydrogen atoms follows the baryon density field, semi-…
Early Dark Energy Effects on the 21cm Signal
Tal Adi, Jordan Flitter, Ely D. Kovetz
Early dark energy (EDE) is one of the leading models proposed to resolve the perplexing Hubble tension. Despite extensive scrutiny and testing against various observables, conclusi…
Probing Dark Relativistic Species and Their Interactions with Dark Matter through CMB and 21cm surveys
Hugo Plombat, Théo Simon, Jordan Flitter +1
We investigate the sensitivity of the 21cm power spectrum from cosmic dawn and the epoch of reionization to models of free-streaming dark radiation (parameterized through $N_{\rm e…
Constraints on the fuzzy dark matter mass window from high-redshift observables
Hovav Lazare, Jordan Flitter, Ely D. Kovetz
We use a combination of high-redshift observables to extract the strongest constraints to date on the fraction of axion fuzzy dark matter (FDM) in the mass window $10^{-26}\,\mathr…
Effects of feedback-free starburst galaxies on the 21-cm signal and reionization history
Sarah Libanore, Jordan Flitter, Ely D. Kovetz +2
Different star-formation models at Cosmic Dawn produce detectable signatures in the observables of upcoming 21-cm experiments. In this work, we consider the physical scenario of fe…
21cmFirstCLASS II. Early linear fluctuations of the 21cm signal
Jordan Flitter, Ely D. Kovetz
In a companion paper we introduce 21cmFirstCLASS, a new code for computing the 21-cm anisotropies, assembled from the merger of the two popular codes 21cmFAST and CLASS. Unlike the…
21cmFirstCLASS I. Cosmological tool for CDM and beyond
Jordan Flitter, Ely D. Kovetz
In this work we present 21cmFirstCLASS, a modified version of 21cmFAST, the most popular code in the literature for computing the anisotropies of the 21-cm signal. Our code uses th…
21-cm fluctuations from primordial magnetic fields
Hector Afonso G. Cruz, Tal Adi, Jordan Flitter +2
The fluid forces associated with primordial magnetic fields (PMFs) generate small-scale fluctuations in the primordial density field, which add to the linear matter…
Magnetic Fields from Compensated Isocurvature Perturbations
Jordan Flitter, Cyril Creque-Sarbinowski, Marc Kamionkowski +1
Compensated isocurvature perturbations (CIPs) are perturbations to the primordial baryon density that are accompanied by dark-matter-density perturbations so that the total matter…
Closing the window on fuzzy dark matter with the 21cm signal
Jordan Flitter, Ely D. Kovetz
Fuzzy dark matter (FDM) is a well motivated candidate for dark matter (DM) as its tiny mass and large de-Broglie wavelength suppress small-scale matter fluctuations, thereby solvin…
Exploring delaying and heating effects on the 21-cm signature of fuzzy dark matter
Debanjan Sarkar, Jordan Flitter, Ely D. Kovetz
In the fuzzy dark matter (FDM) model, dark matter is composed of ultra-light particles with a de Broglie wavelength of kpc, above which it behaves like cold dark matter (CDM)…
Outliers in the LIGO Black Hole Mass Function from Coagulation in Dense Clusters
Jordan Flitter, Julian B. Muñoz, Ely D. Kovetz
The advanced LIGO O3a run catalog has been recently published, and it includes several events with unexpected mass properties, including mergers with individual masses in the lower…
