-- interacting scalar tensor dark energy
Masroor C. Pookkillath, Nandan Roy
We study the effect of adding an interaction in the term of Horndeski theory, where the propagation of gravitational waves are not modified. We derive the background and pert…
Theory of interacting vector dark energy and fluid
Masroor C. Pookkillath, Kazuya Koyama
In this work, we study interaction between dark energy and dark matter, where dark energy is described by a massive vector field, and dark matter is modelled as a fluid. We present…
The Lunar Gravitational-wave Antenna: Mission Studies and Science Case
Parameswaran Ajith, Pau Amaro Seoane, Manuel Arca Sedda +83
The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the size…
Gravitational collapse and formation of a black hole in a type II minimally modified gravity theory
Antonio De Felice, Kei-ichi Maeda, Shinji Mukohyama +1
We study the spherically symmetric collapse of a cloud of dust in VCDM, a class of gravitational theories with two local physical degrees of freedom. We find that the collapse corr…
Extended minimal theories of massive gravity
Antonio De Felice, Shinji Mukohyama, Masroor C. Pookkillath
In this work, we introduce a class of extended Minimal Theories of Massive Gravity (eMTMG), without requiring a priori that the theory should admit the same homogeneous and isotrop…
VCDM and Cuscuton
Antonio De Felice, Kei-ichi Maeda, Shinji Mukohyama +1
We investigate two Type-IIa Minimally Modified Gravity theories, namely VCDM and Cuscuton theories. We confirm that all acceptable Cuscuton solutions are always solutions for VCDM…
