63. On the hosts of neutron star mergers in the nearby Universe

Lorenzo Cavallo

28/09/2022, 11:00

Oral contribution

In the last years, with the advent of multi-messenger astrophysics, the characterisation of binary systems of neutron stars has become central in various fields such as gravitational waves, gramma-ray bursts (GRBs), and the chemical evolution of galaxies. In this work, we explore possible observational proxies that can be used to infer some characteristics of the delay time distribution (DTD)...

91. Quantum noise reduction in Gravitational Wave Interferometers

Barbara Garaventa (Università and INFN Genova)

28/09/2022, 11:20

Oral contribution

The sensitivity of gravitational wave detectors is ultimately limited by
the quantum noise, which arises from the quantum nature of light and it is driven by vacuum fluctuations of the optical field entering from the dark port of the interferometer.
Quantum noise has two complementary features: the shot noise, which depends on phase fluctuations of the optical field disturbing the detector...

72. The multimessenger astrophysics potential of the JUNO experiment

Marta Colomer Molla (ULB (IIHE))

28/09/2022, 11:40

Oral contribution

JUNO will be the largest ever built liquid scintillator detector for neutrino physics. It will be sensitive to various astrophysical neutrino sources, including solar neutrinos, the diffuse supernova neutrino background, pre-supernova neutrinos and the all-flavor neutrino flux from a Galactic core-collapse supernova (CCSN) with high statistics. For the purpose of maximizing the physics reach...

92. Fast emulation of two-point angular statistics for photometric galaxy surveys

Biggio Luca (ETH Zurich)

28/09/2022, 12:00

Oral contribution

We develop a set of machine-learning based cosmological emulators, to obtain fast model predictions for the C(ℓ) angular power spectrum coefficients characterising tomographic observations of galaxy clustering and weak gravitational lensing from multi-band photometric surveys (and their cross-correlation). A set of neural networks are trained to map cosmological parameters into the...

77. Semi-analytic modeling of kilonovae with the radiative transfer equations

Mr Giacomo Ricigliano (Institut für Kernphysik, Technische Universität Darmstadt, Schlossgartenstr. 2, 64289 Darmstadt, Germany)

28/09/2022, 12:25

Oral contribution

Matter expelled from binary neutron star (BNS) and black hole-neutron star (BHNS) mergers is one confirmed site capable of harboring r-process nucleosynthesis in the universe, due to its extreme conditions and abundance of neutrons. The freshly produced nuclei are unstable and undergo nuclear decay, releasing an amount of energy sufficient to power a thermal transient known as kilonova (KN). A...
