Spinning extremal dyonic black holes in Einstein-Maxwell-dilaton theory
Jose Luis Blázquez-Salcedo, Carlos Herdeiro, Eugen Radu +2
We propose a general framework for the study of asymptotically flat spinning dyonic {\it extremal} black holes (eBHs) in Einstein-Maxwell-dilaton theory. Restricting to the s…
Scaling solutions for gauge invariant flow equations in dilaton quantum gravity
Yadikaer Maitiniyazi, Christof Wetterich, Masatoshi Yamada
We discuss the ultraviolet fixed point of asymptotically safe dilaton quantum gravity. It differs from the Reuter fixed point by the dependence of the Planck mass on a scalar field…
Emergence of dynamical tensor fields in composite models of gravity
Yadikaer Maitiniyazi, Masatoshi Yamada
We investigate composite models of gravity and explore how dynamical tensor fields can emerge within the functional renormalization group framework. We consider two prototype model…
QCD chiral phase diagram from weak functional renormalization group
Yuepeng Guan, Masatoshi Yamada
We investigate the QCD chiral phase transition at finite temperature and finite baryon density using the functional Renormalization Group (fRG). While conventional fRG studies ofte…
Water Maser Disk and a Supermassive Black Hole at the Nucleus of the Active Galaxy NGC 7738
Rinka Ito, Yusuke Miyamoto, Naomasa Nakai +2
We present the results of very long baseline interferometry (VLBI) observations of water vapor masers in the nucleus of the LINER galaxy NGC 7738. The red- and blue-shifted and new…
Far-infrared probing with PRIMA into particle acceleration associated with relativistic jets from active galactic nuclei
Naoki Isobe, Takao Nakagawa, Motoki Kino +3
It is presented that the Probe far-Infrared Mission for Astrophysics (PRIMA) has a high potential to study particle acceleration phenomena associated with jets emanating from activ…
