Recent star formation in UCM galaxies (Perez-Gonzalez+, 2003)
We present the integrated properties of the stellar populations in the Universidad Complutense de Madrid (UCM) Survey galaxies. Applying the techniques...
Recent variability of the central star of the planetary nebula NGC 2346.
The authors report photoelectric and CCD photometry of V651 Mon, the central star of the planetary nebula NGC 2346, made in April - May and November, 1992...
Reconciling a Significant Hierarchical Assembly of Massive Early-Type Galaxies at z ≲ 1 with Mass Downsizing
Hierarchical models predict that massive early-type galaxies (mETGs) are the latest systems to be in place into the cosmic scenario (below z ˜ 0. 5)...
Reconstructing Galactic Star Formation Histories from Star Cluster Age- and Mass-Distributions
Observations show a relation between the brightest young star cluster and the present overall star formation rate of a galaxy. A possible explanation would be...
Reconstructing the mass accretion histories of nearby red nuggets with their globular cluster systems
It is generally recognized that massive galaxies form through a combination of in-situ collapse and ex-situ accretion. The in-situ component forms early, where...
Reconstructing the optical spectral variability of gamma-ray blazars
Blazars are a subclass of active galactic nuclei (AGNs) with a relativistically boosted jet pointing towards the Earth. They are one of the most violent and...
Reconstructing the stellar mass distributions of galaxies using S4G IRAC 3.6 and 4.5 μm images: the conversion from light to mass
We present a new approach for estimating the 3.6 μm stellar mass-to-light ratio Υ3.6 in terms of the [3.6]-[4.5] colors of old stellar populations. Our approach...
