72. Are we prepared to observe the next Galactic Supernova? (online talk)

Massimo Della Valle (INAF)

13/06/2023, 15:00

I will briefly review some of the observational facts of Supernovae from the perspective of multi-messenger astronomy, such as future optical and neutrino observations. Based on the current estimates of the supernova rate, some predictions are presented and discussed.

21. Hubble Tension challenge in the modern cosmology: possible solutions

Gennady Bisnovatyi-Kogan (Space Research Institute Rus. Acad. Sci., Moscow, Russia)

One of the problems in the modern cosmology is a so-called Hubble tension (HT), which is the difference between values of the present Hubble constant H0, measured by observation of the universe at redshift z ≤1, and the same value measured by observations of a distant universe by observations of CMB fluctuations corresponding to z ≌1100. We suggest that this Tension may be explained by...

14. Pair-balance model for relativistic shocks and its application to astrophysical sources

Evgeny Derishev (Institute of Applied Physics, Nizhny Novgorod, Russia)

13/06/2023, 16:00

Among astrophysical objects whose emission originates from relativistic shocks are active galactic nuclei, gamma-ray bursts, and pulsar winds. Their exceptionally broad spectra are due to synchrotron and inverse Compton emission of accelerated leptons. Although these radiation processes are common in space, the relativistic shocks and shear flows possess an efficient feedback mechanism that...

52. The James Webb Space Telescope: status and science results (online talk)

Prof. Massimo Stiavelli (Space Telescope Science Institute, USA)

13/06/2023, 17:00

I will briefly describe the James Webb Space Telescope and its status. I will provide an overview of its major science results, or planned observations, in areas that will impact cosmology and fundamental physics.

38. The Science Promise Now Being Realized After JWST's Decades of Challenges (online talk)

Garth Illingworth (UCSC)

13/06/2023, 17:30

The James Webb Space Telescope is an astronomy mission that exceeds all others in capability. The first science results from JWST have already rewritten the science history books. JWST is astonishingly complex, yet it exceeds its requirements in essentially all areas. Its flawless launch and deployments are a testament to the engineering and management commitment of thousands of people in the...
