My name is Vitalia Ann Conners, and my pronouns are she/her.
I am graduating from Rochester Institute of Technology with a BS in #Physics. I have conducted #research in #PulsarTiming for detection of #GravitationalWaves, and I am currently completing my capstone project in #curriculum and interest analysis for introductory-level #astronomy courses. I have successfully completed courses in Extragalactic Astrophysics & Cosmology, General Relativity, and Observational Astronomy.
Pulsar time does not need to receive satellite signals to create a time scale. This can be used to synchronize the electricity grid.

Nice new preprint summarising the current status of #pulsar timing experiments from around the world, looking out across the field’s landscape and highlighting results and challenges.
Some good reading before our upcoming conference in June.

The stability of the spin of pulsars and the precision with which these spins can be determined, allows many unique tests of interest to physics and astrophysics. Perhaps the most challenging and revolutionary of these, is the detection of nanohertz gravitational waves. An increasing number of efforts to detect and study long-period gravitational waves by timing an array of pulsars have been ongoing for several decades and the field is moving ever closer to actual gravitational-wave science. In this review article, we summarise the state of this field by presenting the current sensitivity to gravitational waves and by reviewing recent progress along the multiple lines of research that are part of the continuous push towards greater sensitivity. We also briefly review some of the most recent efforts at astrophysical interpretation of the most recent GW estimates derived from pulsar timing.
A pulsar timing array, but instead of actual real pulsars, send out a bunch of precise atomic clocks in all directions of the Solar System and measure their 'ticks' at a central receiving station.
This idea reported in this pre-print aims to assess the 0.1–10 Hz GW band.
Gravitational-wave astronomy has developed enormously over the last decade with the first detections across different frequency bands, but has yet to access $0.1-10$ $\mathrm{Hz}$ gravitational waves. Gravitational waves in this band are emitted by some of the most enigmatic sources, including intermediate-mass binary black hole mergers, early inspiralling compact binaries, and possibly cosmic inflation. To tap this exciting band, we propose the construction of a detector based on pulsar timing principles, the Artificial Precision Timing Array (APTA). We envision APTA as a solar system array of artificial "pulsars"$-$precision-clock-carrying satellites that emit pulsing electromagnetic signals towards Earth or other centrum. In this fundamental study, we estimate the clock precision needed for APTA to successfully detect gravitational waves. Our results suggest that a clock relative uncertainty of $10^{-17}$, which is currently attainable, would be sufficient for APTA to surpass LISA's sensitivity in the decihertz band and observe $10^3-10^4$ $\mathrm{M}_\odot$ black hole mergers. Future atomic clock technology realistically expected in the next decade would enable the detection of an increasingly diverse set of astrophysical sources, including stellar-mass compact binaries that merge in the LIGO-Virgo-KAGRA band, extreme-mass-ratio inspirals, and Type Ia supernovae. This work opens up a new area of research into designing and constructing artificial gravitational-wave detectors relying on the successful principles of pulsar timing.

Yesterday I gave my first PhD talk at the Astronomical Society of Australia’s Annual Science Meeting on my fav millisecond pulsar - PSR J1713+0747.
The pulsar that threw a tantrum!
Millisecond pulsars are used in pulsar timing arrays as they’re considered stable rotators over the long term. That is vote to helping us search for gravitational wave backgrounds - the big news that we announced last week.
But this very well know millisecond pulsar decided to undergo a massive magnetospheric reconfiguration in 2021 - only the second millisecond pulsar that we know off to exhibit this strange behavior!
In my PhD I will be exploring to see why this happened and if other millisecond pulsars might be doing this on a smaller scale. Maybe they’re not so stable after all … ask me again in three years!

I am excited for the upcoming news from pulsar timing arrays on their search for #GravitationalWaves. Results from International Pulsar Timing Array teams will be shared at 0:00 UTC. I don't know what these will be. However… 1/🧵
Well, since we are bracing for the impact of an imminent major announcement on pulsars and, maybe, some gravitational wave background, why not enjoy this 2004 special Science Magazine issue on pulsars!
