Hace 3 días · Shortly after Schmidt’s discovery, the mechanism powering quasars—accretion of matter by gravity onto supermassive black holes—was independently proposed by Russian astronomers Yakov Zel’dovich and Igor Novikov and Austrian American astronomer Edwin Salpeter.
Hace 3 días · His work in this area was spurred by a visit to Moscow and discussions with Yakov Borisovich Zel'dovich and Alexei Starobinsky, whose work showed that according to the uncertainty principle, rotating black holes emit particles.
Hace 5 días · Abstract. Physics-informed neural networks (PINNs) are a class of scientific machine learning that utilizes differential equations in loss formulations to model physical quantities. Despite recent developments, complex phenomena such as high-Reynolds-number (high- Re R e) flow remain a modeling challenge without the use of high ...

Sunyaev and Yakov Zel'dovich study the inverse Compton scattering of microwave background photons by hot electrons (see Sunyaev–Zel'dovich effect). 1983 – Researchers from the Cambridge Radio Astronomy Group and the Owens Valley Radio Observatory first detect the Sunyaev–Zel'dovich effect from clusters of galaxies .

Aaronson was one of the first astronomers to attempt to image dark matter ...
Hace 5 días · Pole Telescope Sunyaev-Zel’dovich observations found that the CC fraction in a sample of clusters at 0.3 <z<1.3 is re-markably stable although the mass of clusters has increased by a factor of ∼4 over the past 9 Gyr (Ruppin et al.2021). This suggests that the CC disruption is balanced well by
