Cmb targets after planck

We show that a combination of the simplest $\alpha$-attractors and KKLTI models related to Dp-brane inflation covers most of the area in the ($n_{s}$, $r$) space favored by Planck 2018. Expand abstract.

Simplified optical configuration for a sloshing-speedmeter-enhanced gravitational wave detector

We propose a new optical configuration for an interferometric gravitational wave detector based on the speedmeter concept using a sloshing cavity. Expand abstract.

Gravitational wave and collider signals in complex two-Higgs doublet model with dynamical CP-violation at finite temperature

Gravitational wave in complementary to collider signals can help to pin down the underlying phase transition dynamics or different patterns. Expand abstract.

The high-energy collision of black holes in higher dimensions

We compute the gravitational wave energy $E_{\rm rad}$ radiated in head-on collisions of equal-mass, nonspinning black holes in up to $D=8$ dimensional asymptotically flat spacetimes for boost velocities $v$ up to about $90\,\%$ of the speed of light. Expand abstract.

Testing BEC Dark Matter with Gravitational Waves

We show that the constraints obtained in this way are quite tight, if the dark matter field oscillates freely, whereas they are substantially weakened, if the oscillations are damped by the non-minimal coupling. Expand abstract.

Measuring the neutron star equation of state with gravitational waves: the first forty binary neutron star mergers

Gravitational waves from binary neutron star coalescences contain rich information about matter at supranuclear densities encoded by the neutron star equation of state. Expand abstract.

Waveform of gravitational waves in the ghost-free parity-violating gravities

Gravitational waves (GWs) provide an excellent opportunity to test the gravity in the strong gravitational fields. Expand abstract.

Gravitational Waves as a Probe of Left-Right Symmetry Breaking

Left-right symmetry at high energy scales is a well-motivated extension of the Standard Model. Expand abstract.

Electroweak phase transition with composite Higgs models: calculability, gravitational waves and collider searches

We study the strong first order electroweak phase transition (SFOEWPT) with the $SO(6)/SO(5)$ composite Higgs model, whose scalar sector contains one Higgs doublet and one real singlet. Expand abstract.

Analytic Waveforms for Eccentric Gravitational Wave Bursts

We here present the first analytic effective fly-by (EFB) waveforms designed to accurately capture the burst of gravitational radiation from the closest approach of highly eccentric compact binaries. Expand abstract.
