## Title: *Cosmology with Love*
## Reporter: Shao-Jiang Wang
## Abstract
I will try to explain the definition of internal and external parameters of CBC, including general GW detector response w.r.t various coordinate frame and related physical insights for inference. it depends on time to talk about geometrical interpretation of parameter errors in ArXiv 2104.01897.
In this journal club, I will introduce briefly a new GW dark siren method using a binary Love relation for the binary neutron star merger. The redshift information could be extracted between the observer-frame chirp mass from gravitational waveform and the source-frame mass from the Love relatioins.

## Title: *Gravitational waves from resonant amplification of curvature perturbations during inflation*
## Reporter: Zhi-Zhang Peng
## Abstract
In this talk, I will introduce my recent work about the quasinormal mode of charged Gauss-Bonnet de sitter black hole spacetime. Using quasinormal mode, we can determine the stability of the black hole in different dimensions. And we confirmed that BF bound violation will lead to instability of spacetime.
In this seminar, I will introduce my recent work about scalar-induced gravitational waves(GWs) from a single-field inflationary model with oscillatory potential. We compute the energy spectra of induced GWs produced both during inflation and in the radiation-dominated era, and we compare the differences between them.

## Title: *No Inner-Horizon theorem for Anisotropic Black Holes with Charged Vector Hairs*
## Reporter: Cheng-Hu Ge
## Abstract
In this seminar, I will introduce some progress of our work. We consider a Anisotropic black holes model with charged vector hair. With the conserved charge and assumption of smoothness, we prove a no inner-horizon theorem. We also investigate asymptotic behavior of fields around the singularity and the interior dynamics.
