Waveform degeneracy of binary systems and Lagrange three-body systems

Carlos Jaimel Doctolero, Ian Vega

A particular solution to the three-body problem is the circular Lagrange three-body system, where the masses move in circular orbits such that they always constitute an equilateral…

Extreme-mass ratio inspirals in Schwarzschild - de Sitter spacetime I: Weak-field orbits

John Adrian N. Villanueva, Ian Vega

The inspiral of a compact object into a black hole is a key source of low - frequency gravitational waves for future space-based detectors like LISA. While models of this process h…

Exact Regions of Superradiant Instability of Kerr-Newman Black Holes and Massive Scalar Fields

John Adrian B. Baybay, Kevin T. Grosvenor

We investigate the superradiant instability of Kerr-Newman black holes in the presence of a massive, charged scalar field using the Vieira-Bezerra-Kokkotas (VBK) method. We study t…

Measurable Parameter Combinations of Environmentally-dephased EMRI Gravitational-Wave Signals

Marco Immanuel B. Rivera, Reinabelle C. Reyes

The future space-borne Laser Interferometer Space Antenna (LISA) is expected to detect gravitational waves (GW) from Extreme Mass Ratio Inspiral (EMRI) binaries which may live in n…

Quantum and higher curvature corrections to the anti-de Sitter black hole

Kristian Hauser A. Villegas, Reginald Christian Bernardo

Black holes exert quantum pressure coming from the nonlocal gravity correction. We investigate this nonlocal correction for black holes in anti-de Sitter (AdS) spacetime and its du…

Electromagnetic quasinormal modes of Schwarzschild-anti-de Sitter black holes: Bifurcations, spectral similarity, and exact solutions in the large black hole limit

Sean Fortuna, Ian Vega

We revisit the peculiar electromagnetic quasinormal mode spectrum of an asymptotically anti-de Sitter Schwarzschild black hole. Recent numerical calculations have shown that some q…

Inflationary quantum dynamics and backreaction using a classical-quantum correspondence

Reginald Christian Bernardo

We study inflationary dynamics using a recently introduced classical-quantum correspondence for investigating the backreaction of a quantum mechanical degree of freedom to a classi…

Well-tempered teleparallel Horndeski cosmology: a teleparallel variation to the cosmological constant problem

Reginald Christian Bernardo, Jackson Levi Said, Maria Caruana +1

Well-tempering is a promising classical method of dynamically screening an arbitrarily large vacuum energy and generating a late-time, low energy de Sitter vacuum state. In this pa…

Gravitational wave signatures from dark sector interactions

Reginald Christian Bernardo

We show that the gravitational waves generated by the perturbations of general relativistic black holes can be considered as a direct probe of the existence of dark sector interact…

Self-tuning kinetic gravity braiding: Cosmological dynamics, shift symmetry, and the tadpole

Reginald Christian Bernardo

We study the self-tuning subclass of kinetic gravity braiding and obtain robust predictions on self-tuning and dynamics in the tadpole-free shift symmetric sector of the theory. In…

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…
