New infra-red enhancements in 4-derivative gravity
Alberto Salvio, Alessandro Strumia, Hardi Veermae
4-derivative gravity provides a renormalizable theory of quantum gravity at the price of introducing a physical ghost, which could admit a sensible positive-energy quantization. To…
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…
Light Primordial Exotic Compact Objects as All Dark Matter
Martti Raidal, Sergey Solodukhin, Ville Vaskonen +1
The radiation emitted by horizonless exotic compact objects (ECOs), such as wormholes, 2-2-holes, fuzzballs, gravastars, boson stars, collapsed polymers, superspinars etc., is expe…
Wormholes in conformal gravity
Manuel Hohmann, Christian Pfeifer, Martti Raidal +1
We present a new class of solutions for static spherically symmetric wormhole spacetimes in conformal gravity and outline a detailed method for their construction. As an explicit e…
