Laboratory for Astrophysics
We simulate interstellar clouds with special plasma expansions and chemical reactions on icy dust grains to be measured in ultra-high vacuum setups. This provides the data necessary to guide and interpret astronomical observations and to model reaction networks in space. [Harold Linnartz]

Probing the properties of dark matter particles with astrophysical observations
It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

Astrophysical plasma modeling of the hot Universe: Advances and challenges in high-resolution X-ray spectroscopy
Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Astronomy in corona times: 'All the big telescopes were at a standstill.'
Astronomer Ignas Snellen studies exoplanets using telescope observations. But how is that possible when all the big telescopes are more or less at a standstill? Luckily, he has contact from home with a robot telescope in Mexico and his WIFI is finally working well.

Ingredients of the planet-formation puzzle
High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

The alignment of galaxies across all scales
Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

Origin of Neutrino Signal Remains a Mystery
Physicists have studied the astrophysical neutrino signal as reported by the IceCube collaboration from a different angle with their ANTARES detector. The Milky Way centre was an obvious prime suspect to be a source, but this hypothesis is now only closer to debunked than confirmed. Publication in Physical…

Chemistry between stars and planets
In the large gas clouds between the stars, chemical reactions take place under extreme conditions, giving rise to both small molecules, such as water and common salt, as well as large complex molecules that can serve as the building blocks of life. This is known as astrochemistry and it is something…

Exo-planets, star and planet formation
At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…
