A NSF-funded Physics Frontiers Center using pulsars to search for low-frequency gravitational waves! They/Them/Theirs

Lucas Brown, graduate student at Tufts University, has updated the iconic pulsar map originally seen on the Voyager golden record to include the pulsars from NANOGrav's data sets. Check out this great way to visualize our data! You can see how much the array has grown over the years 🔭🧪

NANOGrav congratulates the LISA Consortium on ESA’s approval, advancing the space-based LISA gravitational wave observatory. We look forward to exploring the gravitational universe alongside LVK Consortium and LISA 🔭

Capturing the ripples of spacetime: LISA gets go-ahead

Today, ESA’s Science Programme Committee approved the Laser Interferometer Space Antenna (LISA) mission, the first scientific endeavour to detect and study gravitational waves from space.

Jocelyn Bell Burnell transformed astronomy OTD in 1967 when she made the first observation of a pulsar. She and advisor Antony Hewish initially dubbed the object LGM-1 (“Little Green Men”) for its regular signal, but soon identified it as a rotating, magnetized neutron star. 🔭 🧪 👩‍🔬

A black and white photo of Jocelyn Bell Burnell looking at a printout in front of the large radio dish she used. She is wearing cat's-eye glasses with her brown hair pulled back. Her head is turned towards the camera and she is smiling.The printout where Bell and Hewish noticed the regular signal associated with the pulsar.It is a green-yellow graph paper with a staticky red line showing occasional spikes.
There are hand annotations labeling the spikes and recording the time and date of each one.

The image on the cover of the Joy Division album "Unknown Pleasures" is from a plot that radio astronomer Harold Craft made for his PhD dissertation, using data collected at Arecibo while studying the pulsar Jocelyn Bell Burnell discovered OTD in 1967.🧪 🔭 👩‍🔬

The cover of the Joy Division album
"Unknown Pleasures." It features a white
"stack plot" on a black background. The lines, which record data from a radio telescope, form what looks like a mountain range.

From William Lamb: Post-detection of a gravitational wave background, pulsar timing arrays could detect individual sources of gravitational waves, called Continuous Waves. Let’s find out what properties we expect them to have! 🔭 astrobites.org/2023/10/12/c...
