A Relativistic Tensorial Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +5
In a series of recent papers it was shown that several aspects of Dark Matter (DM) phenomenology, such as the velocity profiles of individual dwarfs and spiral galaxies, the scalin…
Modified gravity in galaxy clusters: Joint analysis of Hydrostatics and Caustics
Minahil Adil Butt, Sandeep Haridasu, Yacer Boumechta +4
We present a comprehensive joint analysis of two distinct methodologies for measuring the mass of galaxy clusters: hydrostatic measurements and caustic techniques. We show that by…
Ultra-compact Objects of Non-minimally Coupled Dark Matter
Francesco Benetti, Andrea Lapi, Samuele Silveravalle +1
In the framework of a collisionless dark matter fluid which is non-minimally coupled to gravity, we investigate the existence and properties of static, spherically symmetric soluti…
A Relativistic Scalar Model for Fractional Interaction between Dark Matter and Gravity
Francesco Benetti, Andrea Lapi, Giovanni Gandolfi +1
In a series of recent papers we put forward a ``fractional gravity'' framework striking an intermediate course between a modified gravity theory and an exotic dark matter (DM) scen…
Mass Modeling and Kinematics of Galaxy Clusters in Modified Gravity
Lorenzo Pizzuti, Yacer Boumechta, Sandeep Haridasu +6
The chameleon screening mechanism has been constrained many a time using dynamic and kinematic galaxy cluster observables. Current constraints are, however, insensitive to differen…
Caustic and hydrostatic mass bias: Implications for modified gravity
Minahil Adil Butt, Balakrishna S. Haridasu, Yacer Boumechta +4
We propose and perform a joint analysis of the two different mass estimates of galaxy clusters, namely the hydrostatic and caustic techniques. Firstly, we show comprehensively that…
