The first Multi-Messenger Continuous Gravitational-Wave Workshop will be held from 11-13 July 2023 at Nikhef/ University of Amsterdam.

The first aim of this workshop is to bring together people inside and outside the LIGO/Virgo/KAGRA collaborations working on anything related to continuous gravitational waves, and to facilitate connections with astronomers that provide the necessary electromagnetic observations that enable us to search for continuous waves.

The second aim of this workshop is to create a tutorials about how continuous-wave data analysis is done that will be accessible to anyone interested in getting involved in searches for continuous waves, as well as to broaden the understanding even amongst continuous-wave scientists about how these searches actually work.

We welcome abstracts from the community, and especially for early career scientists, for whom we hope to be able to provide some registration fee waivers. If you would like to request this support, please indicate so upon registering.

Wide-parameter search using SOAP and Machine Learning [Bayley, presentation slides]

PyFstat and intro slides [Keitel, Tenorio]

Line Hunting (slides 16-19, and download this file) [Neunzert]

Binary ephemerides generation [Killestein, Steeghs, presentation slides]

Matched filtering periodic signals [Krolak]

Pulsar Timing [Possenti, Corongiu, presentation slides]

  • At the link, there is a file containing a Virtual Machine with all the necessary files, as well as the instructions to install that on VirtualBox.
  • Observation files are at 10cm (while removing the 20cm files) in order to make the package light enough. Once the virtual machine is installed, in the tree directory under the account "student" one can find all the instructions, in sequence, to reproduce what was done in the lecture.
  • Packages cannot be run on macs with M1/M2 chips.

Invited Speakers:

  • Joseph Bayley (University of Glasgow)
  • David Keitel (University of the Balearic Islands)
  • Andrzej Krolak (Polish Academy of Sciences)
  • Ansel Neunzert (Caltech)
  • Andrea Possenti (INAF, Cagliari) 
  • Danny Steeghs (University of Warkwick) 



  • Review on continuous gravitational-wave searches
  • Radio pulsar timing
  • Scorpius X-1
  • Neutron star astrophysics
  • NANOGrav data analysis and results
  • Gravitational-wave probes of dark matter and primordial black holes
  • Direct detection of dark matter
  • Detector characterization for continuous-wave searches
  • Multi-messenger probes of neutron star Equation of States



We look forward to welcoming you in Amsterdam!
