Chaotic exits from a weakly magnetized Schwarzschild black hole
Joshua Bautista, Ian Vega
A charged particle kicked from an initial circular orbit around a weakly magnetized Schwarzschild black hole undergoes transient chaotic motion before either getting captured by th…
Stealth black holes in shift symmetric kinetic gravity braiding
Reginald Christian Bernardo, John Celestial, Ian Vega
We derive all hairy stealth black holes in the most general second-order, shift symmetric, scalar-tensor theory with luminally propagating gravitational waves, often called kinetic…
Hair-dressing Horndeski: an approach to hairy solutions in cubic Horndeski gravity
Reginald Christian Bernardo, Ian Vega
In obtaining exact solutions in gravitational theories containing arbitrary model functions, such as Horndeski gravity, one usually starts by prescribing the model functions of the…
Weak gravitational lensing by two-power-law densities using the Gauss-Bonnet theorem
Karlo de Leon, Ian Vega
We study the weak-field deflection of light by mass distributions described by two-power-law densities , where and are non-negative integers. Ne…
Tailoring cosmologies in cubic shift-symmetric Horndeski gravity
Reginald Christian Bernardo, Ian Vega
We present a method for furnishing flat Friedman-Robertson-Walker spacetimes with nearly arbitrary dynamics in an important subclass of cubic Horndeski theory -- specifically shift…
Self-force on a scalar charge in a circular orbit about a Reissner-Nordström black hole
Jezreel Castillo, Ian Vega, Barry Wardell
Motivated by applications to the study of self-force effects in scalar-tensor theories of gravity, we calculate the self-force exerted on a scalar charge in a circular orbit about…
