NGC 5128 (Cen A) is the nearest giant elliptical galaxy and one of the brightest extragalactic radio sources in the sky, boasting a prominent dust lane and jets emanating from its nuclear supermassive black hole. In this paper, we construct the star... Read More about The Complex Star Formation History of the Halo of NGC 5128 (Cen A).

Monthly Notices of the Royal Astronomical Society, 533(1), 1-26. https://doi.org/10.1093/mnras/stae1767

We report the spectroscopic confirmation and fundamental properties of TOI$-$757 b, a mini$-$Neptune on a 17.5$-$d orbit transiting a bright star ($V\, =\, 9.7$ mag) discovered by the TESS mission. We acquired high$-$precision radial velocity measure... Read More about TOI–757 b: an eccentric transiting mini–Neptune on a 17.5–d orbit.

Astronomy & Astrophysics, 686, Article A230. https://doi.org/10.1051/0004-6361/202449307

Context. Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of planetary systems. The wider separation between these planets a... Read More about NGTS-30b/TOI-4862b: An ~1 Gyr old 98-day transiting warm Jupiter.
