Footprints in the sand: What can globular clusters tell us about NGC 4753 past? [PDF]
, 2015 NGC 4753 is a bright (M_V approx -22.3) lenticular galaxy. It is a very interesting target to test different theories of formation of lenticular galaxies, due to its low-density environment and complex structure. We perform the first comprehensive study of NGC 4753 globular cluster system (GCS), using Gemini/GMOS and CTIO/MosaicII images.

Urban Science, 2018 At the beginning of the economic crisis in 2008, the number of foreclosures and evictions increased dramatically in Spain. The severe economic situation and the lack of mitigation measures by public institutions seemed to be the main causes. However, the

Intra Cluster Globular Clusters around NGC 1399 in Fornax? [PDF]
, 2007 We investigate whether the globular clusters (GCs) in the recently published sample of GCs in the Fornax cluster by Bergond and coworkers are indeed intra-cluster objects. We combine the catalogue of radial velocity measurements by Bergond et al. with our CTIO MOSAIC photometry in the Washington system and analyse the relation of metal-poor and metal ...

Ultra-Compact Dwarfs around NGC 3268 [PDF]
, 2014 We present radial velocities (from Gemini/GMOS) of the second sample of ultra-compact dwarfs (UCDs) and bright globular clusters (GCs) in the Antlia cluster. Twenty-three objects are located around the giant elliptical NGC 3268, and one is close to the fainter lenticular NGC 3273.

The number of globular clusters around the iconic UDG DF44 is as expected for dwarf galaxies [PDF]
, 2020 There is a growing consensus that the vast majority of ultra-diffuse galaxies (UDGs) are dwarf galaxies. However, there remain a few UDGs that seem to be special in terms of their globular cluster (GC) systems. In particular, according to some authors, certain UDGs exhibit large GC populations when compared to expectations from their stellar (or total)

The central kiloparsec of starbursts and AGN: The La Palma connection [PDF]
, 2001 We describe selected highlights of the international conference ``The Central Kiloparsec of Starbursts and AGN: The La Palma Connection'', held in May 2001 in Los Cancajos on the Spanish island of La Palma.

Dynamic simulation and exergetic analysis of a solar thermal collector installation
Alexandria Engineering Journal, 2022 Solar collectors are active solar devices which help reducing the energy consumption in buildings. In this paper, a real installation of solar collectors is analysed under different collector array configurations.

VLT photometry in the Antlia Cluster: the giant ellipticals NGC 3258 and NGC 3268 and their globular cluster systems [PDF]
, 2008 We present a deep VLT photometry in the regions surrounding the two dominant galaxies of the Antlia cluster, the giant ellipticals NGC 3258 and NGC 3268. We construct the luminosity functions of their globular cluster systems (GCSs) and determine their distances through the turn-over magnitudes. These distances are in good agreement with those obtained

PARAFAC2$\times$N: Coupled Decomposition of Multi-modal Data with Drift in N Modes [PDF]
arXiv, 2022 Reliable analysis of comprehensive two-dimensional gas chromatography - time-of-flight mass spectrometry (GC$\times$GC-TOFMS) data is considered to be a major bottleneck for its widespread application. For multiple samples, GC$\times$GC-TOFMS data for specific chromatographic regions manifests as a 4th order tensor of I mass spectral acquisitions, J ...
