The dearth of high-mass hydrogen-atmosphere metal-polluted white dwarfs within 40 pc
Tim Cunningham, Pier-Emmanuel Tremblay, Mairi O'Brien +7
We present a population synthesis model which addresses the different mass distributions of the metal-polluted and non-metal-polluted hydrogen-atmosphere white dwarfs identified in…
The D-material universe
Thomas Elghozi, Nick E. Mavromatos, Mairi Sakellariadou +1
In a previous publication by some of the authors (N.E.M., M.S. and M.F.Y.), we have argued that the "D-material universe", that is a model of a brane world propagating in a higher-…
Stringy Models of Modified Gravity: Space-time defects and Structure Formation
Nick E. Mavromatos, Mairi Sakellariadou, Muhammad Furqaan Yusaf
Starting from microscopic models of space-time foam, based on brane universes propagating in bulk space-times populated by D0-brane defects ("D-particles"), we arrive at effective…
Confronting MOND and TeVeS with strong gravitational lensing over galactic scales: an extended survey
Ignacio Ferreras, Nick Mavromatos, Mairi Sakellariadou +1
The validity of MOND and TeVeS models of modified gravity has been recently tested by using lensing techniques, with the conclusion that a non-trivial component in the form of dark…
Incompatibility of Rotation Curves with Gravitational Lensing for TeVeS
Ignacio Ferreras, Nick E. Mavromatos, Mairi Sakellariadou +1
We constrain the one-parameter class of TeVeS models by testing the theory against both rotation curve and strong gravitational lensing data on galactic scales, remaining fully rel…
Can TeVeS avoid Dark Matter on galactic scales?
Nick E. Mavromatos, Mairi Sakellariadou, Muhammad Furqaan Yusaf
A fully relativistic analysis of gravitational lensing in TeVeS is presented. By estimating the lensing masses for a set of six lenses from the CASTLES database, and then comparing…
