Hot Topics in General Relativity and Gravitation

In this centennial anniversary of General Relativity, we will hold a conference on Hot Topics in General Relativity and Gravitation with the motivation to emphasize the tremendous progresses that have been made in Astrophysics and in Cosmology since Einstein’s discovery of General Relativity (GR) in 1915. This international conference will be held at ICISE as part of the Rencontres du Vietnam. Continua a leggere Hot Topics in General Relativity and Gravitation

First stars, galaxies, and black holes: now and then

Understanding the nature of the first cosmic sources is one of the key questions of Cosmology and Galaxy Formation. During the last years Cosmic Archaeology has opened the possibility to indirectly study these distant sources by catching their living fossils in the Local Universe.

Warm Dark Matter Cosmology in agreement with observations

Warm Dark Matter (WDM) is hot topic in galaxies cosmology and implies novelties in the astrophysical, cosmological particle and nuclear physics context. Warm Dark Matter Cosmology (LWDM) gives the same successfull large scale results and CMB results than Cold Dark Matter (LCDM) and succesfully agrees with the observations at the galactic and small scales.

The Extremes of Black Hole Accretion

Some of the most energetic processes seen in the Universe arise close to a super-massive black hole such as relativistic jets and winds. These are now known to play a key role in determining the growth of galaxies across cosmic time, but the mechanisms by which they are launched remain unclear.

Galaxies of many colours: Star formation across cosmic time

Molecular gas and dust emission add an essential piece of information in the understanding of the star formation processes. This is particularly true for the most obscured and dense star forming regions, where optical and near-IR observations suffer from a large obscuration. The last years have been particularly exciting as (sub-)mm interferometers revealed a large number of molecular lines, offering new proxies to estimate the conditions of star formation.

Probing the Fundamental Nature of Spacetime with the Renormalization Group

Renormalization group methods are a key element of theoretical particle physics and may also be central for constructing a fundamental theory of gravity, e.g., based on Weinberg’s asymptotic safety conjecture. The aim of this program is to bring together theorists and phenomenologists in order to discuss ideas related to the application of the renormalization group in quantum gravity and the consequences of asymptotic safety for cosmology, black holes and a possible ultraviolet completion of the standard model of particle physics including gravity.
