After three years of intense work, a collaboration between the Center
for Computational Relativity and Gravitation [https://ccrg.rit.edu]
(CCRG) at RIT and the Argentine Institute of Radioastronomy (IAR)
[https://www.iar.unlp.edu.ar] have released the first scientific
results of direct observation and extremely accurate measurement of
pulsar periods in the south america. Pulsars are highly rotating
neutron stars with intense magnetic fields that emit notably in
radiowavelenths. Those pulses carry information about the structure of
the neutron stars through interstellar media between the neutron star
and the earth.
A paper just appeared in the Astronomy and Astrophysics journal
with results of the detection of a magnetar XTE J1810-197; a glitch(1)
in the period of the Vela pulsar (J0835-4510); and daily observations
of the millisecond pulsar J0437-4515; as some of the highlights of the
first collaboration article.
CCRG director, Manuela Campanelli and IAR director, Gustavo Romero
signed an agreement to exchange visitors, scientific projects and
data. Observations have been performed remotely from the PuMA-DEN lab
at CCRG by members of the collaboration and data is uploaded to a
dedicated storage computer for further analysis. New hardware and
software upgrades are programmed to increase the sensitivity of the
detections by a factor up to five.
This opens a new research area in RIT and giving more research choices
to undergraduate and graduate students from several MS and PhD
(1) A glitch is a sudden change in the rotational period a the neutron
star, due to a sort of quake leading to changes in the pulsar
period. This is particularly noticeable in young pulsars, like Vela.
