Deciphering the VHE gamma-rays spectra of Extreme High-Frequency peaked BL Lac Objects through a Photohadronic Model
Sarira Sahu, D. I. Páez-Sánchez, A. U. Puga Oliveros +7
Extreme high-frequency peaked BL Lac objects (EHBLs) have their synchrotron peak above keV and their inverse Compton peak extends up to several TeVs. Due to low luminosity…
Thermality of the zero-point length and gravitational selfduality
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
It has been argued that the existence of a zero-point length is the hallmark of quantum gravity. In this letter we suggest a thermal mechanism whereby this quantum of length arises…
Spacetime metric from quantum-gravity corrected Feynman propagators
P. Fernandez de Cordoba, J. M. Isidro, Rudranil Roy
Differentiation of the scalar Feynman propagator with respect to the spacetime coordinates yields the metric on the background spacetime that the scalar particle propagates in. Now…
On the cosmological constant as a quantum operator
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We regard the cosmological fluid within an exponentially expanding FLRW spacetime as the probability fluid of a nonrelativistic Schroedinger field. The scalar Schroedinger particle…
On the cosmological constant of flat FLRW spacetime
P. Fernandez de Cordoba, R. Gallego Torrome, S. Gavasso +1
We consider an exponentially expanding, flat, Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe filled with a free Schroedinger field. The probability fluid of the latter is used…
Hyperbolic space in the Newtonian limit: the cosmological constant
J. C. Castro-Palacio, P. Fernandez de Cordoba, R. Gallego Torrome +1
The cosmological constant and the Boltzmann entropy of a Newtonian Universe filled with a perfect fluid are computed, under the assumption that spatial sections are copies of 3-dim…
