The second data release from the European Pulsar Timing Array IV. Implications for massive black holes, dark matter, and the early Universe

Andrii Neronov, Ke Liu, Jia Liu, Jun Wang, Jongmoon Jang

The European Pulsar Timing Array (EPTA) and Indian Pulsar Timing Array (InPTA) collaborations have measured a low-frequency common signal in the combination of their second and first data releases, respectively, with the correlation properties of a gravita ...

Uncovering a population of gravitational lens galaxies with magnified standard candle SN Zwicky

Cameron Alexander Campbell Lemon, Johannes Richard Cornelis Geerit Kruis, Rémy Elie Joseph

Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching the transient signal of a stellar explosion in a distant galaxy and observing it through a nearly perfe ...

Coupling metric-affine gravity to a Higgs-like scalar field

Sebastian Zell

General relativity (GR) exists in different formulations. They are equivalent in pure gravity but generically lead to distinct predictions once matter is included. After a brief overview of various versions of GR, we focus on metric-affine gravity, which a ...

Euclid : Effects of sample covariance on the number counts of galaxy clusters

Yi Wang, Georges Meylan

Aims. We investigate the contribution of shot-noise and sample variance to uncertainties in the cosmological parameter constraints inferred from cluster number counts, in the context of the Euclid survey. ...

The Navigation of Robotic Fiber Positioners in SDSS-V Project: Design and Implementation

Denis Gillet, Jean-Paul Richard Kneib, Matin Macktoobian

SDSS-V project is one of the major observational cosmological projects which aims to generate the map of the observable universe by collecting spectroscopic data from the sky using optical fibers. Each optical fiber is attached to a robotic positioner to b ...

Measurement of branching fraction and final-state asymmetry for the (B)over-bar(0) -> (KSK -/+)-K-0 pi(+/-) decay

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Sun Hee Kim, Jun Yong Kim, Ke Huang

We report a measurement of the branching fraction and final-state asymmetry for the (B) over bar -> (KSK -/+)-K-0 pi(+/-) decays. The analysis is based on a data sample of 711 fb(-1) collected at the gamma(4S) resonance with the Belle detector at the KEKB ...

Constraining the microlensing effect on time delays with a new time-delay prediction model in H-0 measurements

Frédéric Courbin, Hung-Hsu Chan, Vivien François Bonvin, Martin Raoul Robert Millon, Karina Alexandra Rojas Olate

Time-delay strong lensing provides a unique way to directly measure the Hubble constant (H-0). The precision of the H-0 measurement depends on the uncertainties in the time-delay measurements, the mass distribution of the main deflector(s), and the mass di ...

Ultra-coherent nano-mechanical resonators for quantum optomechanics at room temperature

Amir Hossein Ghadimi

Mechanical oscillators are among the most important scientific tools in the modern physics. From the pioneering experiments in 18th by founding fathers of modern physics such as Newton, Hooke and Cavendish to the ground braking experiments in the 21th cent ...
