A CO J = 2-1 survey of type I post-main-sequence nebulae
Nine type I post-main-sequence nebulae were observed in CO J = 2-1 using the NRAO 12-m antenna at Kitt Peak. It is found that, at the most, 20 percent of type I...
A CO molecular gas wind 340 pc away from the Seyfert 2 nucleus in ESO 420-G13 probes an elusive radio jet
A prominent jet-driven outflow of CO(2-1) molecular gas is found along the kinematic minor axis of the Seyfert 2 galaxy ESO 420-G13, at a distance of 340-600 pc...
A cold massive interstellar cloud within 120 parsecs of the Sun: K I optical and H I radio observations
We first discovered the presence of a particularly massive cloud in the neighborhood of the Sun, close to the Galactic plane in the direction of Perseus, toward...
A collection of model stellar spectra for spectral types B to early-M
Context. Models of stellar spectra are necessary for interpreting light from individual stars, planets, integrated stellar populations, nebulae, and the...
A common explanation of the Hubble tension and anomalous cold spots in the CMB
The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its...
A compact jet at the infrared heart of the prototypical low-luminosity AGN in NGC 1052
The feeble radiative efficiency characteristic of Low-Luminosity Active Galactic Nuclei (LLAGNs) is ascribed to a sub-Eddington accretion rate, typically at log...
A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
Context. One of the goals of the Echelle Spectrograph for Rocky Exoplanets and Stable Spectroscopic Observations (ESPRESSO) Guaranteed Time Observations (GTO)...
A Companion Nuclear Bulge to the Seyfert Ring Galaxy NGC 985
Subarcsecond optical broad band images of the Seyfert galaxy NGC 985 are presented. A second nucleus located 3.8" NW of the Seyfert nucleus is clearly revealed...
