Källén Seminar for Young Astronomers on May 10, 2022 The formation of diverse stellar halos around Milky Way galaxies ABSTRACT The diffuse stellar halo surrounding galaxies provides a unique window into their formation, preserving signatures of past merger events several billion years after they occur. Recent advances in low-surface-brightness imaging have revealed an extensive diversity in extrag

Källén Seminar for Young Astronomers on May 24, 2022 Reconstructing the history of the Milky Way in the era of large spectroscopic surveys ABSTRACT At present, our understanding of the formation history of the MW is limited due to the complexity of observing the imprints of accretion events and of reproducing them in numerical simulations. Moreover, though being the only galaxy, in which the Galac

Källén Seminar for Young Astronomers on May 31, 2022 Chemical diversity of sub-Neptune planets   ABSTRACT The atmospheres of sub-Neptunes are expected to exhibit considerable chemical diversity, beyond what is anticipated for gas-giant exoplanets. In my talk, we explore self-consistent atmosphere-interior models of sub-Neptunes to explore this chemical diversity and apply this knowledge to the ava

Källén Seminar for Young Astronomers on June 7, 2022 Diffuse interstellar bands   ABSTRACT Diffuse interstellar bands (DIBs) are interstellar absorption features that widely exist in the optical and near-infrared wavelength range, for which the origin might be gaseous molecules. However the origin go the DIB carrier is still unknown leading to the longest mystery in stellar spectroscopy. DIBs play

The disturbed outer Milky Way disc In our paper, "The Disturbed Outer Milky Way Disc", myself and my collaborators looked at the strange bumps, clumps and wriggles in the velocity distribution the Milky Way disc, and compared them to some simulations of a recent disc crossing by a perturbing satellite. This movie gives a brief explanation of the main results.   In connection with this paper we sho

Källén Seminar for Young Astronomers on June 14, 2022 On the causal origin of properties of dark matter halos and galaxies   ABSTRACT Large-cosmological simulations, such as Illustris-TNG or Horizon-AGN, allows to draw relations between the formation history of galaxies and their host haloes (number of mergers, formation time) and their properties (galaxy morphology, halo concentration). These rel

Källén Seminar for Young Astronomers on September 6, 2022 Rebounding Cores to Build Star Cluster Multiple Populations   ABSTRACT Multiple stellar populations in star clusters is a widespread phenomenon. They are observed to come in (at least) two flavours: either as multiple star formation episodes observed in young star clusters, or as multiple chemical abundance patterns observed in most old glo

Källén Seminar for Young Astronomers on September 20, 2022 Massive stars, their formation and their multiplicity   ABSTRACT Massive stars are very influential objects, affecting both their local and galactic environments through their creation of the heavy elements and their immense feedback. Furthermore, the lives of massive stars are further complicated by the fact that most of them exist in at

Astronomy research and education has been a part of the Department of Astronomy and Theoretical Physics (ATP) since its formation back in 2010.  Back then the intention was that ATP would be a temporary organizational form, and that it would merge with the Department of Physics within three years.  The planned merger never happened and over a decade later, Lund University still had its physics sub

Postgraduate studies are a vital part of the Department's research activities. The PhD students work in close collaboration with their supervisors and colleagues in small research groups, which very often are parts of much larger international collaborations. Travels to conferences and visits to other institutes or observatories are natural ingredients of the education. Many of our postgraduate st
