Full spectrum of Love numbers of Reissner-Nordstrom black hole in D-dimensions
Minghao Xia, Liang Ma, Yi Pang +1
We present a comprehensive analysis of the full spectrum of tidal Love numbers for Reissner-Nordström (RN) black holes in general spacetime dimensions. By perturbing the Einstein-…
Consistent Four-derivative Heterotic Truncations and the Kerr-Sen Solution
Liang Ma, Yi Pang, Robert J. Saskowski +1
Four-derivative heterotic supergravity (without gauge fields) reduced on a -dimensional torus leads to half-maximal supergravity coupled to vector multiplets, and it is know…
Higher-derivative Heterotic Kerr-Sen Black Holes
Peng-Ju Hu, Liang Ma, Yi Pang +1
We obtain the four-derivative corrections to the Kerr-Sen solution in heterotic supergravity, which includes the Gibbons-Maeda-Garfinkle-Horowitz-Strominger solution as a limiting…
Constraining Cubic Curvature Corrections to General Relativity with Quasi-Periodic Oscillations
Alireza Allahyari, Liang Ma, Shinji Mukohyama +1
We investigate observational constraints on cubic curvature corrections to general relativity by analyzing quasi-periodic oscillations (QPOs) in accreting black hole systems. In pa…
Leading Higher Derivative Corrections to Multipole Moments of Kerr-Newman Black Hole
Liang Ma, Yi Pang, H. Lu
We study the (leading) 4-derivative corrections, including both parity even and odd terms, to electrically-charged Kerr-Newman black holes. The linear perturbative equations are th…
