Using 3D Spectroscopy to Probe the Orbital Structure of Composite Bulges
Detailed imaging and spectroscopic analysis of the centers of nearby S0 and spiral galaxies shows the existence of ``composite bulges'', where both classical...
Using APOGEE Data to Examine Late-K and Early-M Dwarfs
The Apache Point Galactic Evolution Experiment (APOGEE) has obtained high resolution (R~22,500) near-infrared spectra of over 100,000 stars, including a subset...
Using clustering for disperse objects fields segmentation in MIRADAS instrument
Mid-resolution InfRAreD Astronomical Spectrograph (MIRADAS), a near-infrared multi-object spectrograph for Gran Telescopio Canarias (GTC), has 12 deployable...
Using color-magnitude diagrams and spectroscopy to derive star formation histories: VLT observations of Fornax
We undertook a study of the star formation and chemical enrichment history of the Fornax dSph galaxy. We used the VLT with FORS1 to obtain photometry reaching...
Using Globular Clusters to Test Gravity in the Weak Acceleration Regime
We report on the results from an ongoing programme aimed at testing Newton's law of gravity in the low acceleration regime using globular clusters. We find that...
Using globular clusters to test gravity in the weak acceleration regime: NGC 6171
As part of an ongoing program to test Newton’s law of gravity in the low acceleration regime using globular clusters, we present here new results obtained for...
Using Globular Clusters to Test Newton's Law of Gravity
New measurements of the velocity dispersion of the globular cluster ω Centauri allow us to trace its gravitational potential down to an acceleration of 8×10-9...
