Flashing fast: characterising the 2025 outburst of MAXI J1957+032
A. Sanna, G. Illiano, M. C. Baglio +13
MAXI J1957+032 is an accreting millisecond X-ray pulsar that shows brief, recurrent outbursts in an ultra-compact ~1 h orbit. We characterise the 2025 outburst using X-ray timing a…
Euclid: The first statistical census of dusty and massive objects in the ERO/Perseus field
G. Girardi, A. Grazian, G. Rodighiero +175
Our comprehension of the history of star formation at relies on rest-frame UV observations, yet this selection misses the most dusty and massive sources, yielding an incomple…
Euclid preparation: LXXXVII. Non-Gaussianity of 2-point statistics likelihood: Precise analysis of the matter power spectrum distribution
Euclid Collaboration, J. Bel, S. Gouyou Beauchamps +281
We investigate the non-Gaussian features in the distribution of the matter power spectrum multipoles. Using the COVMOS method, we generate 100\,000 mock realisations of dark matter…
Euclid: Exploring observational systematics in cluster cosmology -- a comprehensive analysis of cluster counts and clustering
A. Fumagalli, M. Costanzi, T. Castro +168
This study explores the impact of observational and modelling systematic effects on cluster number counts and cluster clustering and provides model prescriptions for their joint an…
Multiwavelength continuum, emission line and BAL variability with prominent PV absorption in the X-ray-weakest quasar PG0043+039
Wolfram Kollatschny, Norbert Schartel, Malte A. Probst +3
PG0043+039 has been identified as an extremely X-ray-weak quasar and as a peculiar broad-absorption-line quasar based on UV HST spectra. We took simultaneous deep X-ray observation…
Rapid onset of a Comptonisation zone in the repeating tidal disruption event XMMSL2 J140446.9-251135
R. D. Saxton, T. Wevers, S. van Velzen +11
We report here on observations of a tidal disruption event, XMMSL2 J1404-2511, discovered in an XMM-Newton slew, in a quiescent galaxy at z=0.043. X-ray monitoring covered the epoc…
