Mining the kinematics of discs to hunt for planets in formation
Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Carol van Driel Murray over de vrouwen in Romeins Nederland in podcast De Limes Leeft
Een echte mannenwereld, dat is het beeld dat bestaat over de Romeinse tijd in Nederland. Soldaten wonen en werken in de forten en op de wachttorens en verdedigen de grens. Maar waar zijn dan de vrouwen? Er wordt steeds vaker bewijs gevonden dat er wel degelijk vrouwen en kinderen binnen de forten woonden.…

Podcast met Roos van Oosten in Leidsch Dagblad
In de meest recente podcast 'Enkeltje wetenschap', van Universiteit Leiden, treedt Middeleeuws archeoloog Roos van Oosten op. In de podcast, getiteld 'Kopje onder in een Leidse beerput', spreekt ze over het fenomeen dat middeleeuws Leiden een stuk schoner was dan het Leiden vanaf de 17e eeuw.

Opvallende vondst in toekomstige Limes-buurt bij Valkenburg
Naast het grootste aantal waterbouwkundige werken bij elkaar dat in Nederland onderzocht is, is er nog een bijzondere vondst gedaan. Naast een van de opgegraven bruggen stak een stuk leer uit de grond, deze is als een blok uitgegraven en voor verder onderzoek overgebracht naar de Faculteit Archeologie…

Middeleeuws Leiden was schoner dan gedacht
Ons beeld van middeleeuwse steden is dat ze smerig en onhygiënisch waren. Het onderzoek van archeoloog Roos van Oosten wijst echter uit dat een simpel systeem van beerputten voor een relatief goede hygiëne zorgde. In een lang artikel op de website Archaeology.org wordt Roos van Oosten gevolgd tijdens…
