Magellan sp. obs. of galaxies with z~0.95 in UDS
While galaxy clusters are dominated by quiescent galaxies in the local Universe, they show a wide range in quiescent galaxy fraction (QF) at higher redshifts. Here we present... -
Spectrophotometric standard DA white dwarfs
We verified for photometric stability a set of DA white dwarfs with Hubble Space Telescope magnitudes from the near-ultraviolet to the near-infrared and ground-based... -
Stellar contents in the Sh2-112 cloud complex
We present the star formation activity around the emission nebula Sh2-112. At a distance of ~2.1kpc, this HII complex, itself 3pc in radius, is illuminated by the massive star... -
Deep view into Sagittarius dSph with MUSE. III.
We present comprehensive multicomponent dynamical models of M54 (NGC6715), the nuclear star cluster of the Sagittarius (Sgr) dwarf galaxy, which is undergoing a tidal disruption... -
TOI-1450 radial velocities & activity indicators
M-dwarf stars provide us with an ideal opportunity to study nearby small planets. The HUnting for M Dwarf Rocky planets Using MAROON-X (HUMDRUM) survey uses the MAROON-X... -
NIR spectrum of the red L/T VHS J183135.58-551355.9
We present the discovery of VHS J183135.58-551355.9, an L/T transition dwarf identified as a result of its unusually red near-infrared colors (J-K_S_=3.633+/-0.277mag;... -
CO (8-5) spectra of 10 galaxies
This paper summarizes all presently available J_upp_>=5 ^13^CO and accompanying ^12^CO measurements of galaxy centers including new J=6-5 ^13^CO and ^12^CO observations of... -
ZTF DR1 light curves of SNe Type Ia
Type Ia supernovae (SNe Ia) in the nearby Hubble flow are excellent distance indicators in cosmology. The Zwicky Transient Facility (ZTF) has observed a large sample of SNe from... -
Planetary systems study with GALAH surveys
Pioneering photometric, astrometric, and spectroscopic surveys is helping exoplanetary scientists better constrain the fundamental properties of stars within our galaxy and the... -
Element abundances study of Cepheids
Radial abundance gradients provide sound constraints for chemo-dynamical models of galaxies. Azimuthal variations of abundance ratios are solid diagnostics to understand their... -
CHAOS. VII. Large-scale abundance study in M33
The dispersion in chemical abundances provides a very strong constraint on the processes that drive the chemical enrichment of galaxies. Due to its proximity, the spiral galaxy... -
Solar-type stars Halpha line
Excess chromospheric emissions within deep photospheric lines are effective proxies of stellar magnetism for FGK stars. This emission decays with stellar age and is a potential...
