Jonathan Irwin

I am currently a postdoc at the Harvard-Smithsonian Center for Astrophysics, working on the MEarth project (web page coming soon!), a transit survey of nearby M-dwarfs searching for low-mass planets. My boss is Dave Charbonneau, who has a much more interesting web page than I do...

Work

Thesis

The online version

The Monitor Project

The project I worked on for my PhD thesis.

Monitor rotation period data

All the Monitor rotation periods that have been published so far are available here.

The IoA All-Sky Camera

Experimental 24/7 fisheye camera on the roof of the observatory.

Talk slides

Slides (PDF) from various talks I have given.

INT Wide Field Camera archive

Interface to the CASU archives of reduced observations from the Wide Field Camera on the 2.5m Isaac Newton Telescope (INT). Includes the obvservations from the INT Wide Field Survey.

Photography

Astronomy (non-work)

Astronomical Images

A selection of images from the INT wide field camera archives, and the Digitised Sky Survey (DSS).

Three Mirror Telescope

Reasonably up-to-date information on the 3MT, including the documentation for the (very old) CCD system and the new telescope control system.

Only publications where I am lead author are listed below. Please see ADS for the rest. N.B. there are (at least) two other "J. Irwin"s in astronomy...

Old stuff

Radial velocity standards

Lists of radial velocity standards for spectroscopy, with DSS finder charts. This was put together for my benefit, but somebody else might find it useful too.

INT Wide Field Camera catalogue extract script

An experimental interface for extracting cut-outs of a given region of sky in multiple INT WFC passbands, automatically selecting the appropriate observations to use.

INT Wide Field Camera DQC plotter

An experimental interface for making plots of various DQC parameters for observations in the archive.

SuperWASP CLI docs

Documentation for the command-line interface for SuperWASP. This is used by the observation scheduler (and the users) to drive the equipment.
