Progressive Indexes
Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

Light Weighed: On the Statistics and Systematics of Weak Gravitational Lensing
In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Giant galactic outflows and shocks in the Cosmic Web
The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Mogelijk protoplaneet in ‘stellaire baarmoeder’ waargenomen
Waarschijnlijk hebben astronomen met ESO’s Very Large Telescope voor het eerst een planeet-in-wording waargenomen die nog in een dikke schijf van gas en stof genesteld zit. De ontdekking is gedaan door een internationaal team van astronomen, onder wie Matthew Kenworthy van de Universiteit Leiden. Indien…

Leidse sterrenkundigen ontdekken grootste deeltjesversneller in het heelal
Een team van voornamelijk Leidse astronomen heeft de grootste deeltjesversneller in het heelal ontdekt. Zij ontdekten dat bij een frontale botsing van vier gigantische clusters van sterrenstelsels deeltjes versneld worden tot zeer hoge energieën. De energieën zijn meer dan een miljoen maal hoger dan…

Is er zuurstof op exoplaneten? Nieuwe telescoop zoekt het uit
In hoeverre lijkt exoplaneet Proxima b op onze aarde? En is er ook leven te vinden? Astronomen hopen daar antwoorden op te vinden met de nieuwe Europese Extremely Large Telescope (ELT). Met een NWO-onderzoeksfinanciering van 18 miljoen euro kan een Nederlands consortium verder bouwen aan de instrumenten…

Joop Schaye in Volkskrant over reusachtig kosmisch spinnenweb
Het is de grootste structuur in het heelal: een duizelingwekkend web van materie dat sterrenstelsels zoals de Melkweg onderling verbindt. De Leidse Joop Schaye en Michael Maseda waren twee van de astronomen die hielp een piepklein stukje van dit 'kosmische spinnenweb' in beeld te brengen. In de Volkskrant…

Geometry of Vegetation Pattern
One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.
