35. Galactic archeology: overview and chemical evolution

Chiaki Kobayashi (University of Hertfordshire)

9/30/22, 9:00 AM

Oral contribution

27. Prospects of present and future underground labs for nuclear astrophysics

Rosanna Depalo (INFN Legnaro)

9/30/22, 10:00 AM

Oral contribution

62. Planck observations of the Galactic polarized synchrotron emission and constraints on Dark Matter

Alessandro Cuoco (Istituto Nazionale di Fisica Nucleare)

9/30/22, 11:00 AM

Oral contribution

The Planck collaboration has produced precise observations of the polarized synchrotron emission in the microwave band.
This emission is sensitive to the presence of a possible signal from Dark Matter annihilation or decay.
We use, for the first time, synchrotron polarization to constrain the DM annihilation cross section by comparing theoretical predictions with the latest polarization maps...

54. Multimessenger astrophysics at LNS from a nuclear physics point of view

Aurora Tumino (Istituto Nazionale di Fisica Nucleare)

9/30/22, 11:20 AM

Oral contribution

The detection of the gravitational event GW170817 is a turning point in nuclear astrophysics. Its observation triggered the investigation of the bright optical transient AT2017gfo using a broad number of diagnostic tools, opening the era of multimessenger astronomy. In particular, the follow-up of the lightcurve evolution made it possible to pinpoint the contribution from freshly synthesized...

82. New 3D White Dwarf Deflagration Models for Type Iax Supernovae

Fionntan Callan (Queen's University Belfast )

9/30/22, 11:40 AM

Oral contribution

Type Ia supernovae (SNe Ia) play a number of key roles in astrophysics. These include contributing substantially to cosmic nucleosynthesis, injecting kinetic energy in galaxy evolution and acting as cosmological distance indicators. Thanks to modern transient surveys it has become clear that type Ia supernovae are a diverse population with many different explosion scenarios proposed to explain...

85. Looking for Orphan gamma-ray burst in the Rubin LSST data with the FINK alert broker

Dr Johan Bregeon (CNRS/IN2P3/LPSC - Univ. Grenoble Alpes)

9/30/22, 12:00 PM

Oral contribution

Gamma-ray bursts are highly energetic cosmological objects that provide us with different paths towards a better understanding of fundamental physics and the evolution of the universe. The most recent, promising and innovative path developed, consists in estimating the Hubble cosmological constant from gravitational wave events for which the distance can be estimated through electromagnetic...

84. Toward an independent reconstruction of the expansion history of the Universe

Nicola Borghi (University of Bologna)

9/30/22, 12:20 PM

Oral contribution

A cosmological-model independent reconstruction of the expansion history of the Universe can help to shed light on the dark sector and the current cosmological tensions. I will discuss past, present, and future efforts to constrain the Hubble parameter $H(z)$ using two optimal astrophysical probes: cosmic chronometers and gravitational waves. Massive and passive galaxies can be used as...
