30. Line Intensity Mapping targeting astrophysics and cosmology

Caroline Heneka (Universität Hamburg)

Parallel talk

Line Intensity Mapping (LIM) targets the Universe from present time up to redshifts beyond ten when the first galaxies formed, from small to largest scales. Similar to CMB measurements, power spectra of emission line fluctuations tell both about structure growth and underlying cosmology as well as astrophysical processes. Imagine the information encoded in thousands of intensity maps at...

39. A black hole as big as the universe?

Betti Hartmann (Universidade de São Paulo (Brazil) & Universität Oldenburg)

Parallel talk

In this talk, I will discuss black hole solutions that evade the famous "No hair"
theorem and carry - next to mass and charge - additional features on their
horizon in the form of scalar fields. Interestingly, when considering the strong gravity regime, these black holes look as if they were inflating. This leaves the possible
interpretation of a black hole having formed in the early...

40. Early universe cosmology: the no-boundary proposal

Caroline Jonas (Max Planck Institute for Gravitational Physics (Albert Einstein Institute))

06/11/2020, 10:00

Parallel talk

Understanding its origins is one of humanity oldest and most recurrent aspiration. In the latest centuries, physics has enabled us to push further and further this quest for the origins of our universe, resulting in the mid-20th century in the famous theory of the Big Bang and, later, that of inflation.
The Big Bang theory is based on the description of gravitational interaction by General...
