From Boundary Data to Bound States III: Radiative Effects
Gihyuk Cho, Gregor Kälin, Rafael A. Porto
We extend the "boundary-to-bound" (B2B) correspondence to incorporate radiative as well as conservative radiation-reaction effects. We start by deriving a map between the total cha…
Third order post-Newtonian gravitational radiation from two-body scattering: Instantaneous energy and angular momentum radiation
Gihyuk Cho, Subhajit Dandapat, Achamveedu Gopakumar
We compute the third post-Newtonian (3PN) accurate instantaneous contributions to the radiated gravitational wave (GW) energy and angular momentum arising from the hyperbolic passa…
Action-angle variables of a binary black hole with arbitrary eccentricity, spins, and masses at 1.5 post-Newtonian order
Sashwat Tanay, Leo C. Stein, Gihyuk Cho
Accurate and efficient modeling of the dynamics of binary black holes (BBHs) is crucial to their detection through gravitational waves (GWs), with LIGO/Virgo/KAGRA, and LISA in the…
SO(10) Grand Unification with Minimal Dark Matter and Color Octet Scalars
Gi-Chol Cho, Kana Hayami, Nobuchika Okada
The minimal dark matter (MDM) scenario is a very simple framework of physics beyond the Standard Model (SM) to supplement the SM with a DM candidate. In this paper, we consider an…
Electroweak phase transition in a complex singlet extension of the Standard Model with degenerate scalars
Gi-Chol Cho, Chikako Idegawa, Eibun Senaha
We study the feasibility of strong first-order electroweak phase transition (EWPT) in a degenerate-scalar scenario of a complex singlet extension of the Standard Model, in which a…
Gravitational radiation from inspiralling compact objects: Spin-spin effects completed at the next-to-leading post-Newtonian order
Gihyuk Cho, Brian Pardo, Rafael A. Porto
Using the gravitational potential and source multipole moments bilinear in the spins, first computed to next-to-leading order (NLO) in the post-Newtonian (PN) expansion within the…
