The MAVERIC Survey: A Transitional Millisecond Pulsar Candidate in Terzan 5 [PDF]

Astrophysical Journal, 2018
Transitional millisecond pulsars are accreting millisecond pulsars that switch between accreting X-ray binary and millisecond radio pulsar states. Only a handful of these objects have been identified so far.

Effect of low energy availability during three consecutive days of endurance training on iron metabolism in male long distance runners

Physiological Reports, Volume 8, Issue 12, June 2020., 2020
Three consecutive days of endurance training under low energy availability (LEA) decreased the muscle glycogen content and increased the serum hepcidin level in well‐trained male long distance runners. These results suggest that LEA is associated with a risk of exercise‐induced iron deficiency by an elevated hepcidin level in endurance athletes ...

Swinging between rotation and accretion power in a binary millisecond pulsar

EPJ Web of Conferences, 2014
We present the discovery of IGR J18245–2452, the first millisecond pulsar observed to swing between a rotation-powered, radio pulsar state, and an accretion-powered X-ray pulsar state [31]. This transitional source represents the most convincing proof of

The Galactic Millisecond Pulsar Population [PDF]

, 2012
Among the current sample of over 2000 radio pulsars known primarily in the disk of our Galaxy, millisecond pulsars now number almost 200. Due to the phenomenal success of blind surveys of the Galactic field, and targeted searches of Fermi gamma-ray ...

Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST): A Powerful Explorer of Exotic Pulsars

Universe
Located in southern China, the five-hundred-meter aperture spherical radio telescope (FAST) is the world’s most sensitive radio telescope, especially for pulsar observation. Since its commissioning in 2016 and full operation in 2020, it has detected over

Green Bank Telescope Discovery of the Redback Binary Millisecond Pulsar PSR J0212+5321

The Astrophysical Journal, 2023
We report the discovery of a 2.11 ms binary millisecond pulsar during a targeted search of the redback optical candidate coincident with the γ -ray source 3FGL J0212.5+5320 using the Robert C.

The characteristics of millisecond pulsar emission: I. Spectra, pulse shapes and the beaming fraction

, 1998
We have monitored a large sample of millisecond pulsars using the 100-m Effelsberg radio telescope in order to compare their radio emission properties to the slowly rotating population.
