Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating $\delta$ Scuti pulsator, with the goal of measuring the orbital obliquity via the gravity-darkening effect, and constraining the geometric albedo via t

Glitch-induced pulse profile change of PSR J0742-2822 observed from the IAR

Autor: Zubieta, E., García, F., del Palacio, S., Espinoza, C. M., Furlan, S. B. Araujo, Gancio, G., Lousto, C. O., Combi, J. A., Gügercinoğlu, E.

The radio pulsar PSR J0742-2822 is known to exhibit rapid changes between different pulse profile states that correlate with changes in its spin-down rate. However, the connection between these variations and the glitch activity of the pulsar remains
