X TrA through the eyes of MATISSE: More evidence of clumpy molecular layers around C-type asymptotic giant branch stars
V. Răstău, C. Paladini, J. Drevon +22
Aims. The goal of this study is to further the understanding of the wind formation mechanism in asymptotic giant branch (AGB) stars through the analysis of the close environment (w…
First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer
GRAVITY+ Collaboration, :, F. Allouche +137
GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the develop…
Spatially resolved broad line region in a quasar at z=4: Dynamical black hole mass and prominent outflow
GRAVITY+ Collaboration, K. Abd El Dayem, N. Aimar +92
We present the first near-infrared interferometric data of a QSO at z=4. The K-band observations were performed with GRAVITY+ on the VLTI using all four UTs, detecting a differenti…
The Aromatic Infrared Bands around the Wolf-Rayet Binary WR140 Revealed by JWST
Kotomi Taniguchi, Ryan M. Lau, Takashi Onaka +12
We have analyzed the aromatic infrared bands (AIBs) in the 6-11.2 m range around the Wolf-Rayet binary WR140 (d=1.64 kpc) obtained with the James Webb Space Telescope (JWST) Mid…
Revealing Io's Surface using JWST-NIRISS Aperture Masking Interferometry and Neural Network Deconvolution
J. Sanchez-Bermudez, I. dePater, A. Conrad +6
Io is one of Jupiter's largest moons and the most volcanically active body in the Solar System. Its very active surface has hot spots produced by volcanic eruptions popping up at s…
JWST interferometric imaging reveals the dusty disk obscuring the supermassive black hole of the Circinus galaxy
Enrique Lopez-Rodriguez, Joel Sanchez-Bermudez, Omaira Gonzalez-Martin +6
The dusty and molecular torus is one of the most elusive structures surrounding supermassive black holes, yet its importance is unequivocal for understanding feedback and accretion…
Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets
David Trevascus, Sarah Blunt, Valentin Christiaens +22
Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…
Dynamic Imprints of Colliding-wind Dust Formation from WR140
Emma P. Lieb, Ryan M. Lau, Jennifer L. Hoffman +24
Carbon-rich Wolf-Rayet binaries are a prominent source of carbonaceous dust that contribute to the dust budget of galaxies. The "textbook" example of an episodic dust producing WR…
