The detection of an older population in the Magellanic Bridge [PDF]

, 2013
The Magellanic system comprises the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the less frequently observed Magellanic Bridge and Magellanic Stream. The Bridge is traced by neutral gas and has an observed stellar component, while

New 6 and 3-cm radio-continuum maps of the Small Magellanic Cloud - part II: Point source catalogue [PDF]

Serbian Astronomical Journal, 2012
We present two new catalogues of radio-continuum sources in the field of the Small Magellanic Cloud (SMC). These catalogues contain sources found at 4800 MHz (λ=6cm) and 8640 MHz (λ=3cm).

Spectral Feature Extraction Using Partial and General Method

Advances in Astronomy, Volume 2021, Issue 1, 2021., 2021
With the rapid growth in astronomical spectra produced by large sky survey telescopes, traditional manual classification processes can no longer fulfill the requirements of precision and efficiency of spectral classification. There is an urgent need to employ machine learning approaches to conduct automated spectral classification tasks.

THE STUDY OF GALACTIC BEAT CEPHEIDS WITH APPLICATION OF ITS RESULTS TO THOSE IN THE MAGELLANIC CLOUDS

Odessa Astronomical Publications, 2014
A thorough study of the correlation between P1=P0 ratio, fundamental period, and chemical composition (abundances of metals that compose Z) was conducted to investigate the significance of the iron-peak elements on the ratio. The results suggested a more

New 6 and 3-cm radio-continuum maps of the Small Magellanic Cloud, Part I: The maps [PDF]

Serbian Astronomical Journal, 2011
We present new 6 and 3-cm radio-continuum maps of the Small Magellanic Cloud (SMC), created with the "peeling" technique and a joint deconvolution. The maps have resolutions of 3000 and 2000 and r.m.s., noise of 0.7 and 0.8 mJy/beam at 6 and 3 ...

Discovery of 14 radio pulsars in a survey of the Magellanic Clouds [PDF]

, 2006
A systematic survey of the Large and Small Magellanic Clouds for radio pulsars using the Parkes radio telescope and the 20-cm multibeam receiver has resulted in the discovery of 14 pulsars and the redetection of five of the eight previously known spin ...

Planetary Nebulae in the Small Magellanic Cloud [PDF]

, 2016
We analyse the planetary nebulae (PNe) population of the Small Magellanic Cloud (SMC), based on evolutionary models of stars with metallicities in the range $10^{-3} \leq Z \leq 4\times 10^{-3}$ and mass $0.9 M\odot < M < 8M\odot$, evolved through the ...

The Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE): The Dust Extinction Curve from Red Clump Stars [PDF]

, 2017
We use Hubble Space Telescope (HST) observations of red clump stars taken as part of the Small Magellanic Cloud Investigation of Dust and Gas Evolution (SMIDGE) program to measure the average dust extinction curve in a ~ 200 pc x 100 pc region in the ...

Tiny-Scale Molecular Structures in the Magellanic Clouds (Part 1) [PDF]

, 2004
We report on the {\small FUSE} detections of the HD and CO molecules {\bf on the lines of sight towards three Large Magellanic stars}: Sk $-$67D05, Sk $-$68D135, and Sk $-$69D246.

Small Dwarf Galaxies Within Larger Dwarfs: Why Some Are Luminous While Most Go Dark [PDF]

, 2008
We consider the possibility that the Magellanic Clouds were the largest members of a group of dwarf galaxies that entered the Milky Way (MW) halo at late times. Seven of the eleven brightest satellites of the MW may have been part of this system.
