Supermassive Black Hole Winds in X-rays -- SUBWAYS. VI. Interplay between the soft X-ray excess and ultra-fast outflows

V. E. Gianolli, P-O. Petrucci, S. Bianchi +42

We present a broadband, multiwavelength study of the interplay between the soft X-ray excess (SE), ultra-fast outflows (UFOs), and warm absorbers (WAs) in 21 active galactic nuclei…

Tracing Accretion and Inner-Disk Gas Evolution in the Orion Nebula via Br-alpha and CO

Konstantin V. Getman, Maria Claudia Ramirez-Tannus, Jenny Frediani +17

We present a systematic spectroscopic study of hydrogen Brackett-alpha (Br-alpha) and carbon monoxide (CO) fundamental-band (4.3-5.2 micron) emission from a homogeneous sample of 0…

Chandra-JWST Probing the Effects of Moderate X-Ray Superflares on Protoplanetary Disks

Konstantin V. Getman, Kevin L. Luhman, Bayron Portilla-Revelo +17

Powerful X-ray flares from young stars may rapidly alter the physical and chemical conditions of their planet-forming disks, but direct observational tests remain scarce. We presen…

Asymptotic limits in class- theories and non-Abelian Hodge theory

Thomas W. Grimm, Amineh Mohseni

We develop a non-Abelian Hodge-theoretic refinement of asymptotic limits in type- class- theories, enriching the geometric description of the degenerating UV curve w…

Euclid Quick Data Release (Q1) Euclid spectroscopy of quasars. 2. Physical properties from spectral fitting

Euclid Collaboration, J. Calhau, G. Calderone +312

A substantial volume of spectroscopic data has become available with the Euclid Data Release (Q1), which represents a unique opportunity to study quasars (QSOs) in the Euclid Deep…

HERschel Observations of Edge-on Spirals (HEROES). I: Far-infrared morphology and dust mass determination

J. Verstappen, J. Fritz, M. Baes +11

Context. Edge-on spiral galaxies with prominent dust lanes provide us with an excellent opportunity to study the distribution and properties of the dust within them. The HEROES pro…

An extremely primitive halo star

E. Caffau, P. Bonifacio, P. François +11

The early Universe had a chemical composition consisting of hydrogen, helium and traces of lithium1, almost all other elements were created in stars and supernovae. The mass fracti…
