Constraints on ALPs and excited dark matter from the EDGES 21-cm absorption signal
Andi Hektor, Gert Hütsi, Luca Marzola +1
The recent observation of the 21-cm absorption signal by the EDGES experiment provides a new observational window into the dynamics of the young Universe. Based on this result, we…
Constraints on primordial black hole dark matter from Galactic center X-ray observations
Andi Hektor, Gert Hütsi, Martti Raidal
Surprisingly high masses of the black holes inferred from the LIGO & Virgo gravitational wave measurements have lead to speculations that the observed mergers might be due to ${\ca…
The EDGES 21 cm Anomaly and Properties of Dark Matter
Sean Fraser, Andi Hektor, Gert Hütsi +8
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at , if cosmological, requires the existence of new physics. The possible…
Constraining Primordial Black Holes with the EDGES 21-cm Absorption Signal
Andi Hektor, Gert Hütsi, Luca Marzola +3
The EDGES experiment has recently measured an anomalous global 21-cm spectrum due to hydrogen absorptions at redshifts of about . Model independently, the unusually low t…
