We present the analysis of Halpha3, an Halpha imaging survey galaxies selected from HI ALFALFA Survey in Coma Supercluster. By using line as a tracer "instantaneous" star formation, complemented with optical colors SDSS we explore hypothesis that morphological sequence progressively earlier type, lower gas-content exists neighborhood cluster, specific formation activity decreasing increasing local galaxy density and velocity dispersion. In dwarf regime (8.5<\log(M*)< 9.5) identify 4-step...
We present results derived from the first multi-chord stellar occultation by trans-Neptunian object (229762) 2007 UK$_{126}$, observed on 2014 November 15. The event was Research and Education Collaborative Occultation Network (RECON) project International Timing Association (IOTA) collaborators throughout United States. Use of two different data analysis methods obtain a satisfactory fit to seven chords, yelding an elliptical chords with equatorial radius $R=338_{-10} ^{+15}$ km equivalent...
Abstract We have used Spitzer images of a sample 68 barred spiral galaxies in the local universe to make systematic measurements bar length and strength. combine these with precise determinations corotation radii associated bars, taken from our previous study, which phase change radial inflow outflow gas at corotation, based on high-resolution two-dimensional velocity fields H α Fabry–Pérot spectrometer. After presenting histograms derived parameters, we study their dependence galaxy...
We report new near-IR integral field spectroscopy of the central starburst region barred spiral galaxy M83 obtained with Cambridge Infra-Red Panoramic Survey Spectrograph (CIRPASS) on Gemini-South, which we analyse in conjunction GHαFaS Fabry–Perot data, an Anglo-Australian Telescope (AAT) IRIS2 Ks-band image, and near- mid-IR imaging from Hubble Spitzer space telescopes. The bulk current star formation activity is hidden optical view by dust extinction, but seen to north nucleus. This being...
We have combined observations of the Antennae galaxies from radio interferometer ALMA (Atacama Large Millimeter/submillimeter Array) and optical GH$\alpha$FaS (Galaxy H$\alpha$ Fabry-Perot System). The two sets comparable angular spectral resolutions, enabling us to identify 142 giant molecular clouds (GMCs) 303 HII regions. measured, compared, their basic physical properties (radius, velocity dispersion, luminosity). For regions, we find regimes, one for masses $>10^{5.4}...
We present the integrated Hα emission line profile for 157 H ii regions in central 3.4 × arcmin2 of galaxy M83 (NGC 5236). Using Fabry–Perot interferometer GHαFaS, on 4.2-m William Herschel Telescope La Palma, we show importance a good characterization instrumental response function study shapes. The luminosity–velocity dispersion relation is also studied, and log(L)–log(σ) plane do not find linear relation, but an upper envelope with equation log(LHα) = 0.9 log(σ) + 38.1. For adopted...
We have observed the Arp 270 system (NGC 3395 & NGC 3396) in H{\alpha} emission using GH{\alpha}FaS Fabry-Perot spectrometer on 4.2m William Herschel Telescope (La Palma). In 3396, which is edge-on to us, we detect gas inflow towards centre, and also axially confined opposed outflows, characteristic of galactic superwinds, go examine possibility that there a shrouded AGN nucleus. The combination surface brightness, velocity dispersion information enabled us measure radii, FWHM, masses 108...
We have designed and installed a new set of actuators for the suspension primary mirror 2.1-m telescope at San Pedro Mártir. This active optics system has allowed us to correct low-order aberrations identified by several wave-front analysis techniques.
High-dispersion time-resolved spectroscopy of the dwarf nova SS Cygni was obtained during two consecutive days at end an outburst. The emission lines present a double-peaked profile with peak-to-peak separation |$526 \pm 14\,\text{ km s}^{-1}.$| have complex structure which includes narrow asymmetric component coming from hot spot in accretion disc or chromosphere red dwarf. radial velocity analysis yields semi-amplitude values |$K_\text{em}=96 5\,\text{ s}^{-1}$| for wings Hγ and Hβ,...
We present measurements of internal proper motions at more than 500 positions NGC 2392, the Eskimo Nebula, based on images acquired with WFPC2 board Hubble Space Telescope two epochs separated by 7.695 yr. Comparisons observations clearly show expansion nebula. measured amplitude and direction motion local structures in nebula determining their relative shift during that interval. In order to assess potential uncertainties determination this object, general, were performed using different...
A detailed multi-wavelength study of the properties triple-peaked AGN Mrk\,622 showing different aspects nuclear emission region is presented. Radio, near- and mid-infrared, optical X-ray data has been considered for analysis. In optical, WHAN diagnostic diagrams show that three peaks are strong active galactic nuclei since EW $H{\alpha}$ $>$\,6 \AA\, $\log$ [NII]$\lambda$6584/H$\alpha$\, ratio $>$\,-0.4. Optical variability both continuum flux intensity narrow lines detected in a time-span...
We have studied the nuclear region of previously detected dual AGN system in galaxy pair IRAS 05589+2828 and 2MASX J06021107+2828382 through new optical spectroscopy observations, along with radio X-ray archival data. Our multiwavelength data strongly suggest that Sy1 \iras\, (z=0.0330$\pm$0.0002) conforms to a Sy2 \twomas\, (z=0.0334$\pm$0.0001) projected separation obtained from 20.08\arcsec\, ($\sim$13.3\,kpc). Analysis spectra reveals faint narrow extended emission H$\alpha$ [OIII]...
We present an analysis of the familiar method analyzing out‐of‐focus stellar images to align Cassegrain reflector telescopes. measure asymmetry in image as difference positions centers bordering circles. By exact raytracing we find that can be expressed a linear combination tip/tilt and displacement secondary mirror. Furthermore surprisingly, does not depend on amount defocus, so only two parameters are needed telescope. These telescope design parameters. Finally, report experimental results...
Mrk\,622 is a Compton Thick AGN and double-peaked narrow emission line galaxy, thus dual candidate. In this work, new optical long-slit spectroscopic observations clearly show that object rather triple peaked with both blue red shifted lines, as well much narrower centred at the host galaxy systemic velocity. The average velocity offset between components $\sim$500 km\,s$^{-1}$, which producing apparent lines. These two are in loci of Baldwin, Phillips \& Terlevich (BPT) diagrams found...
La pandemia del Covid-19, obligó a las instituciones educativas desarrollar estrategias de continuidad para sus procesos formativos, centradas en la preservación salud y mantener e incluso mejorar calidad aprendizaje.

Our Research Group in Electromagnetism and Communications is involved a project dealing with the channel characterization data transmission from Spanish Antarctic Base (62.6S, 60.4W) to Spain (40.8N, 0.5E). In this paper results of third sounding survey corresponding 22 consecutive days January February 2006 are presented. Frequencies range 4 18 Mhz, bandwidths up 16.5 Khz have been probed.
