Pizza lunch talks

The API pizza lunch talks are informal, weekly meetings where people give a half hour overview of their work (or perhaps a totally different topic), in an informal atmosphere. Pizza meeting is not a colloquium, but is intended to inform and stimulate discussion about the topic.

More information (including tips for speakers, contact points and the latest API articles & circulars).

Upcoming lunch talks

Primordial atmospheres of forming rocky planets: the feedback from the pebble destruction

Andrius Popovas — Niels Bohr Institute, Kopenhagen, Denmark

In this talk I will discuss the daily lives of primordial atmospheres, surrounding the cores of forming rocky planets: how do they look like, why are they there, how they grow and evolve, how they interact with the surrounding disk, and what are we doing to better understand them.

FFTs, Omniscopes, and Far-Future Astronomy

Liam Connor — API -- UvA

Telescopes make good use of Fourier transforms. Whether they are done digitally, or in analog with optics, FTs allow us to reconstruct chromatic and spatial information of electric fields on the sky. In recent years, Moore’s law has begat a digital age of radio astronomy.

Past lunch talks

Slowly solving a 40 year old mystery in black hole variability

Phil Uttley — API -- UvA

Almost since the discovery of the first confirmed accreting black holes in X-ray binary systems, we have known that their X-ray emission varies rapidly and that the variations seen in higher energy X-rays lag behind the variations seen in lower-energy X-rays.

The late evolution of cataclysmic variables

Juan Hernandez — API -- UvA

Accreting white dwarfs from main-sequence companions (commonly known as cataclysmic variables, CVs) are one of the most abundant interacting binaries in our Galaxy. Recent observational breakthroughs have provided direct tests to evolution model predictions of CVs.

Numerical Simulations of the Merging Cluster of Galaxies Cygnus A

Timo Halbesma — API -- UvA

The archetype FR-II galaxy Cygnus A lies in a moderately rich cluster of galaxies in which two subclusters are about to undergo a major merger. The active galactic nucleus (AGN) Cygnus A shows strong interactions with the cluster environment, a process called AGN feedback.

Unusual scattering variability of the Crab Pulsar

Laura Driessen — API -- UvA

The Crab pulsar is a well-known, bright pulsar with interesting features such as giant pulses, glitches and anomalous scattering. We observed the Crab at 350MHz over two years with the Westerbork Synthesis Radio Telescope to investigate a period of anomalous scattering that occured from late 2012 to early 2013.
