VISUAL, RED AND INFRARED PHOTOGRAPHIC SURFACE PHOTOMETRY OF NGC 55 AND NGC By Gregory L. Fitzgibbons August Chairman: Stephen T. Gottesman Major Department: Astronomy Detailed photographic surface photometry is presented for the Sculptor Group galaxies NGC 55 and NGC Observations in visual, red and infrared light from long and.

NGC 's starburst has created several super star clusters on NGC 's center (discovered with the aid of the Hubble Space Telescope): one with Visual mass of *10 6 solar masses, and absolute magnitude of at leastand two others with 5*10 4 solar masses and absolute magnitudes around ; later studies have discovered an even more massive Constellation: Sculptor.

Red and infrared photographic surface photometry of NGC 55 and NGC 253 book had a cold but enjoyable night. One of the others is a high school teacher, and several of his students and some parents joined us for a while.

From follow-up spectroscopy with Hydra-CTIO, we find 31 new Visual clusters in NGCNGCand NGCbringing the total number of known Sculptor Group globular clusters to   The surface digital photometry for NGC and NGC is given. The luminosity profiles and colour gradients are discussed and compared.

It is concluded that NGC differs from Red and infrared photographic surface photometry of NGC 55 and NGC 253 bookboth in the extension and intensity of the star burst event because of the kinematical behaviour of the captured : J.

Sérsic, C. Donzelli. We made CCD surface photometry in B, V, R and I filters for two Sb barred galaxies: NGC and IC We obtained isophotal maps, inclination, orientation, integrated magnitudes, and diameters.

NGCnear the more famous Bubble Nebula, is located in the constellation is located about 9, light-years from Earth. Red and infrared photographic surface photometry of NGC 55 and NGC 253 book is home to the biggest yet discovered protostar which is about times the size of the Solar is located in the Cepheus' Arm of the Milky Way and is probably part of the Cassiopeia OB2 complex.

OPTICAL AND NEAR-INFRARED SURFACE PHOTOMETRY OF QUIESCENT DWARF GALAXIES We have presented optical and near-IR surface photometry for quiescent dwarf galaxies (dEs). For this purpose, we have obtained optical images from SDSS (Sloan Digital Sky Survey) and near-IR images (H & K bands) from Magpop-ITP (Multi.

This image from Orion Telescopes & Binoculars' of NGC - Sculptor Galaxy was taken by Greg Bradburn using an Orion ED80T CF Triplet Apochromatic Refractor Telescope, an Orion Atlas EQ-G Computerized GoTo Telescope Mount and an Orion Magnificent Mini Deluxe AutoGuider Package. The high dust content accompanies frantic star formation, earning NGC the designation of a starburst galaxy.

NGC is also known to be a strong source of high-energy x-rays and gamma rays, likely due to massive black holes near the galaxy's center. Tomorrow's picture: pixels in space.

Detailed surface photometry of the edge-on SO galaxy NGC was carried out in B and V color bands by a computerized digital method. The luminosity distribution was analyzed in the standard manner and then decomposed into the spheroid and the disk components.

Video Camera photometry obtained with the Kitt Peak National Observatory m telescope has been reduced and analyzed for the old open cluster NGC and the globular cluster NGC For the former, the CM diagram near the turnoff bears a striking similarity to that of NGCwith the inference that the two are similar in metallicity.

Abstract. I present first results of an infrared photometric study of the young starburst cluster NGC The infrared color-magnitude and color-color diagrams reveal a predominantly early-type stellar population and about 20 stars with significant IR excess which could be Herbig Ae/Be : Andrea Moneti.

We report here CCD I-band time-series photometry of a young (2−5 Myr) cluster NGC to identify and understand the variability of pre-main-sequence (PMS) stars. The I-band photometry, down to ∼ mag, enables us to probe the variability towards the lower mass end (∼ M⊙) of the PMS by: 5.

infrared (NIR) surface brightness decompositions and rotation For NGC we considered just the G. Moriondo et al.: Near-infrared surface photometry of early-type spiral galaxies. II The disk In the case of an infinitely thin exponential disk, the rotation.

In time the blue stars will disappear. In this way the blue regions in NGC trace the places where stars are actively being formed today. NGC is bright enough to be visible in binoculars from a dark site, and even the smallest of telescopes reveal a smaller version of M The following is a list of notable galaxies.

There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order ofin our Local Supercluster, and an estimated one to two trillion in all of the observable universe.

The infrared light emitted by NGC NASA/JPL-Caltech Looking for the infrared light emitted by NGC helps cut through more of the dust and gas to see where stars are : Kelsey Kennedy.

NGC 's warped disk and faint extensions give the appearance of past gravitational interactions with neighboring galaxies. Like the much closer and brighter Sculptor galaxy NGCtendrils of dust appear to rise from a galactic disk sprinkled with blue star clusters and pinkish star forming regions.
