ALMA detection of the dusty object silhouetted against the S0 galaxy NGC 3269 in the Antlia cluster
L. K. Haikala, R. Salinas, T. Richtler +3
An intriguing silhouette of a small dust patch can be seen against the disk of the S0 galaxy NGC 3269 in the Antlia cluster in optical images. The images do not provide any clue as…
New type II Cepheids from VVV data towards the Galactic center
V. F. Braga, R. Contreras Ramos, D. Minniti +5
The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree withi…
New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data
V. F. Braga, A. Bhardwaj, R. Contreras Ramos +5
Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. We trace t…
On the RR Lyrae stars in globulars: V. the complete Near-Infrared (JHKs) census of omega Centauri RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +35
We present a new complete Near-Infrared (NIR, ) census of RR Lyrae stars (RRLs) in the globular Cen (NGC 5139). We collected 15,472 images with 4-8m class telesc…
Development of an IMS Type Device for Volatile Organic Compunds Detection: Simulation and Comparision of the Ion Distributions
Guillermo P. Ortiz, Carlos A. Rinaldi, Norberto G. Boggio +6
Ion Mobility Spectrometry (IMS) is a well-known, sensitive and rapid technique to detect dangerous organic compounds. We propose a system in which a crown type discharge generates…
