Unveiling the secrets of Jupiter with the Juno mission
With more than 4000 exoplanets found and about 2-dozens of planets with detected atmospheric chemical species, we moved from an era of discovery to a new era of exoplanet characterisation. On the othe...

X-ray study of supernova remnants as remnants of supernovae
Supernovae (SNe) are one of the most energetic explosion events in the universe, with the human detectability not only in electromagnetic waves but also neutrino and possibly gravitational waves. They...

The Galactic Cosmic Rays: From MeV to PeV.
Cosmic rays (CRs) is one of the most important component in the interstellar medium (ISM) in our Galaxy. The high energy CRs will interact with the ambient gas and produce gamma-rays, which dominate t...

Probing the Dynamics and Magnetic Fields of Extended Exoplanet Atmospheres
Atmospheric escape is an important process in the evolution of exoplanet atmospheres, especially those orbiting very close to their host stars. However, many aspects of atmospheric escape remain poorl...

The Past, Present, and Future of 21cm Cosmology
Despite tremendous recent progress, gaps remain in our knowledge of our cosmic history. For example, we have yet to make direct observations of Cosmic Dawn or the subsequent Epoch of Reionization. Tog...

The Biggest Splash
In the Milky Way there exists a significant population of old and metal-rich stars on highly eccentric orbits, most likely born in-situ. It is not 100% clear how this in-situ halo population came abou...

The quasi-equilibrium structure of dark matter halos: from theory to observation
Dark matter halos are approximately virialized condensation of dark matter and serve as the building blocks of large scale structure and galaxy formation. These structures, however, are not fully in e...

From halo to intergalactic medium: directly constraining the properties of large-scale gas around high-redshift quasars
At high redshift most of the baryons reside outside galaxies, in an intricated network of sheets, filaments and knots, also known as the Cosmic Web. The direct detection of this large-scale gas struct...
