COSMIC-S: A Photometric Catalog of Observed Stars in the Small Magellanic Cloud

The Astrophysical Journal Supplement Series
The Dark Energy Camera (DECam) is a wide-field instrument mounted on the 4 m V. Blanco Telescope (Cerro Tololo Inter-American Observatory). Its impressive technical characteristics make it one of the most suitable ground-based telescopes for the ...

Untangling Magellanic Streams

The Open Journal of Astrophysics
The Magellanic Stream (MS) is known to contain multiple HI strands and corresponding stellar populations are being discovered. Combining a sample of 17 stars from the H3 (“Hectochelle in the Halo at High Resolution”) survey with 891 stars drawn from the

New 20-cm radio-continuum study of the small Magellanic cloud - part III: Compact Hii regions [PDF]

Serbian Astronomical Journal, 2012
We present and discuss a new catalogue of 48 compact Hii regions in the Small Magellanic Cloud (SMC) and a newly created deep 1420 MHz (λ=20 cm) radio-continuum image of the N19 region located in the southwestern part of the SMC.

New 20-cm radio-continuum study of the Small Magellanic Cloud, part II: Point sources [PDF]

Serbian Astronomical Journal, 2011
We present a new catalogue of radio-continuum sources in the field of the Small Magellanic Cloud (SMC). This catalogue contains sources previously not found in 2370 MHz (λ=13 cm) with sources found at 1400 MHz (λ=20 cm) and 843 MHz (λ=36 cm). 45

The H alpha Galaxy Survey VI. Star-forming companions of nearby field galaxies

, 2008
We present a search for star-forming satellite galaxies that are close enough to their parent galaxies to be considered analogues of the Magellanic Clouds. Our search technique relied on the detection of the satellites in continuum-subtracted narrow-band

The Morphologies of the Small Magellanic Cloud

, 2000
We compare the distribution of stars of different spectral types, and hence mean age, within the central SMC and find that the asymmetric structures are almost exclusively composed of young main sequence stars. Because of the relative lack of older stars

A bright millisecond radio burst of extragalactic origin

, 2007
Pulsar surveys offer one of the few opportunities to monitor even a small fraction (~0.00001) of the radio sky for impulsive burst-like events with millisecond durations.

Dual Directional Expansion of Classical Cepheids in the Small Magellanic Cloud Revealed by Gaia Data Release 3

The Astrophysical Journal Letters
We present the three-dimensional kinematics of classical Cepheids (CCs) in the Small Magellanic Cloud (SMC) using Gaia DR3 data. By crossmatching the CCs obtained from the fourth phase of the Optical Gravitational Lensing Experiment with Gaia DR3, we ...

ABOUT CHEMICAL COMPOSITION OF SUPERGIANT PMMR145 IN SMALL MAGELLANIC CLOUD. OSMIUM.

Odessa Astronomical Publications, 2012
The abundance analysis of six Ksupergiants of the Small Magellanic Cloud (Hill 1997) showed that the heavier elements (La, Ce, Nd, Eu) have the excess relative to iron [El/Fe]=+0.4 dex, on average, for the sample of five stars (PMMR23, PMMR27, PMMR48 ...
