Ly α coupling and heating at cosmic dawn

Shikhar Mittal et al.

Summary: Analyzing the impact of heating due to Ly alpha photons on the global 21-cm signal at cosmic dawn, the study found that even a strong Ly alpha background is consistent with the measurement results from the Experiment to Detect the Global EoR Signal (EDGES). It was also shown that the magnitude of Ly alpha heating is smaller than previously estimated in the literature by two orders of magnitude or more.

Evaporating primordial black holes in gamma ray and neutrino telescopes

Antonio Capanema et al.

Summary: This study reevaluates the signals produced by primordial black holes in their last stages of evaporation in gamma ray and neutrino telescopes, and discusses the impact on existing constraints. The research shows that neutrino telescopes have the capability and advantages in searching for primordial black holes, and proposes correlations of gamma ray and neutrino energy and time profiles as a powerful tool in identifying these black holes.

Global 21cm absorption signal from superconducting cosmic strings

Roxane Theriault et al.

Summary: Research shows that superconducting cosmic strings emit electromagnetic waves during specific periods, affecting the global signal. For string tensions in a specific range, the absorption features of strings can be significantly amplified, with one feature comparable to what was observed in the EDGES experiment.

Influences of accreting primordial black holes on the global 21cm signal in the dark ages

Yupeng Yang

Summary: Accreting PBHs can alter the evolution of the IGM, impacting the global 21 cm signal during the dark ages. Future radio telescopes in lunar orbit or on the farside of the Moon may detect these signals and distinguish them from the standard model after accounting for essential factors like foreground and interference.

Constraints on MeV dark matter and primordial black holes: Inverse Compton signals at the SKA

Bhaskar Dutta et al.

Summary: This study investigates the potential for probing MeV dark matter particles and primordial black holes using photon signals at the upcoming radio telescope SKA. The results show that SKA can significantly improve constraints on dark matter annihilation/decay rate and primordial black hole abundance, with limits independent of assumed magnetic fields within galaxies. Additionally, predicted constraints on diffusion parameters of MeV electrons inside dwarf galaxies are excluded, highlighting the importance of independent observations in different frequency bands.

Press-Schechter primordial black hole mass functions and their observational constraints

Joaquin Sureda et al.

Summary: A modification of the Press-Schechter formalism was presented to derive mass functions for primordial black holes, with additional parameters introduced to accommodate various collapse conditions. The study used observed abundance of supermassive black holes to constrain mass functions and found regions in parameter space where all dark matter can be made up of primordial black holes. Additionally, a method was developed to convert existing constraints on PBH mass fraction into constraints for extended PBH mass functions.

Gas heating from spinning and non-spinning evaporating primordial black holes

Ranjan Laha et al.

Summary: Primordial black holes from the early Universe are considered as a viable dark matter candidate which can span a wide range of masses. Light PBHs with masses around 10^15 g contribute to dark matter and will efficiently evaporate through Hawking radiation, leading to observable signatures. Constraints from dwarf galaxy heating by evaporating PBHs are weaker than previously suggested, and limits on PBH DM abundance are stronger for evaporating spinning PBHs compared to non-spinning PBHs.

Constraints on accreting primordial black holes with the global 21-cm signal

Yupeng Yang

Summary: The study investigates the impact of accreting primordial black holes on the thermal history of the intergalactic medium, potentially affecting the global 21-cm signal during cosmic dawn. By analyzing the global 21-cm signal detected by EDGES, the study establishes upper limits on the abundance of primordial black holes for different mass ranges, with stronger constraints observed for certain mass ranges compared to previous works.

Constraining primordial black holes as dark matter at JUNO

Sai Wang et al.

Summary: The study examines the possibility of using (anti)neutrino signals in the detector of Jiangmen Underground Neutrino Observatory to constrain primordial black holes as dark matter. Among different detection channels, the inverse beta decay is shown to be highly sensitive to the fraction of PBHs contributing to the dark matter abundance. JUNO is expected to provide a significant improvement in constraining PBHs compared to current limits from other experiments.
