Testing Kerr black hole mimickers with quasi-periodic oscillations from GRO J1655-40
Abstract: The measurements of quasi-periodic oscillations (QPOs) provide a quite powerful tool to test the nature of astrophysical black hole candidates in the strong gravitational field regime. In this paper, we use QPOs within...
Hidden Spectral Symmetries and Mode Stability of Subextremal Kerr(-de Sitter) Black Holes
Abstract: We uncover hidden spectral symmetries of the Teukolsky equation in Kerr(-de Sitter) black holes, recently conjectured by Aminov, Grassi and Hatsuda (Ann. Henri Poincaré 23, 1951-1977, 2022, and Gen. Relativ. Grav....
Raman solitons in waveguides with simultaneous quadratic and Kerr nonlinearities
We analyze Raman-induced self-frequency shift in two-component solitons supported by both quadratic and cubic nonlinearities. Treating Raman terms as a perturbation, we derive expressions for soliton velocity and frequency...
Metabolic rewiring in mutant Kras lung cancer.
Lung cancer is the leading cause of cancer-related death worldwide, reflecting an unfortunate combination of very high prevalence and low survival rates, as most cases are diagnosed at advanced stages when treatment efficacy is...

Threshold of complexity and Arnold tongues in Kerr-ring microresonators
We show that the threshold condition for two pump photons to convert into a pair of the sideband ones in Kerr microresonators with high-quality factors breaks the pump laser parameter space into a sequence of narrow in frequency...
KRAS Allelic Imbalance
The identification of therapeutic vulnerabilities in mutant KRAS tumors has proven difficult to achieve. Burgess and colleagues recently reported in Cell that mutant/wild-type Kras allelic dosage determines clonal fitness and...

The Kijowski–Liu–Yau quasi-local mass of the Kerr black hole horizon
We use the isometric embedding of the spatial horizon of fast rotating Kerr
black hole in a hyperbolic space to compute the quasi-local mass of the horizon
for any value of the spin parameter $j=J/m^2$. The mass is...
Surviving the Alamo, Violence Vengeance, and Women’s Solidarity in Emma Pérez’s Forgetting the Alamo, Or, Blood Memory
Adrianna M. Santos
Mar 01, 2019
This article analyzes Chicana feminist texts to frame a discussion of survival as a theoretical concept. Using Emma Pérez’s historical novel Forgetting the Alamo, Or, Blood Memory as a window into the decolonial imaginary, I...

The Kijowski–Liu–Yau quasi-local mass of the Kerr black hole horizon * * Dedicated to Gary Gibbons on the occasion of his 75th birthday.
Abstract: We use an isometric embedding of the cross-over surface of the outer horizon of a rapidly rotating Kerr black hole in a hyperbolic space to compute the quasi-local mass of the horizon for any allowed value of the spin...
Mode Stability for the Teukolsky Equation on Extremal and Subextremal Kerr Spacetimes
Rita Teixeira da Costa
Jul 17, 2020
Abstract: We prove that there are no exponentially growing modes nor modes on the real axis for the Teukolsky equation on Kerr black hole spacetimes, both in the extremal and subextremal case. We also give a quantitative...

Eigenvalue repulsions and quasinormal mode spectra of Kerr-Newman
The frequency spectra of the gravito-electromagnetic perturbations of the
Kerr-Newman (KN) black hole with the slowest decay rate have been computed
recently. It has been found that KN has two families $-$ the photon sphere...
An Innovative Methodological Approach to Analysing Social Media Movements

Changes in perceived scientific consensus shift beliefs about climate change and GM food safety.
Despite an overwhelming scientific consensus, a sizable minority of people doubt that human activity is causing climate change. Communicating the existence of a scientific consensus has been suggested as a way to correct...
