Red and blue shift in spherical and axisymmetric spacetimes and astrophysical constraints
Roberto Giambò, Orlando Luongo, Lorenza Mauro
We compute the red and blue shifts for astrophysical and cosmological sources. In particular, we consider low, intermediate and high gravitational energy domains. Thereby, we handl…

Traversable wormholes with vanishing sound speed in gravity
Salvatore Capozziello, Orlando Luongo, Lorenza Mauro
We derive exact traversable wormhole solutions in the framework of gravity with no exotic matter and with stable conditions over the geometric fluid entering the throat. For…
