The WFI Halpha spectroscopic survey of the Magellanic Clouds: Be stars in SMC open clusters [PDF]

, 2008
At low metallicity, B-type stars show lower loss of mass and, therefore, angular momentum so that it is expected that there are more Be stars in the Magellanic Clouds than in the Milky Way.

Chemical Evolution of the Universe and its Consequences for Gravitational‐Wave Astrophysics

Annalen der Physik, Volume 536, Issue 2, February 2024.
Population properties of double compact object mergers (especially binary black holes) are sensitive to the metallicity dependent cosmic star formation history. The uncertainty of this quantity cannot be ignored and makes the interpretation of current gravitational wave observations difficult.

Scylla. V. Constraints on the Spatial and Temporal Distribution of Bursts and the Interaction History of the Magellanic Clouds from Their Resolved Stellar Populations

The Astrophysical Journal
We measure the star formation histories (SFHs) from the Scylla survey in ∼98,000 pc ^2 and ∼75,000 pc ^2 of the Small Magellanic Cloud (SMC) and Large Magellanic Cloud (LMC), respectively, using deep Hubble Space Telescope imaging (80% complete to > 1 ...

Massive Stars in the Tarantula Nebula: A Rosetta Stone for Extragalactic Supergiant HII Regions

Galaxies, 2019
A review of the properties of the Tarantula Nebula (30 Doradus) in the Large Magellanic Cloud is presented, primarily from the perspective of its massive star content.

The Structure of the Small Magellanic Cloud.

The Astronomical Journal, 1960
In the infrared passband λλ 7000-7600 (103a-U emulsion plus RG8 filter) the 8-inch Schmidt shows the Small Cloud as a quite elliptical patch with some internal structure (Plate I). It is natural to ask whether the Small Cloud is, in fact, a complex system with one component having the essential characteristics of an elliptical galaxy.

Scylla. III. The Outside-in Radial Age Gradient in the Small Magellanic Cloud and the Star Formation Histories of the Main Body, Wing, and Outer Regions

The Astrophysical Journal
The proximity of the Large and Small Magellanic Clouds (LMC and SMC) provides the opportunity to study the impact of dwarf–dwarf interactions on their mass assembly with a unique level of detail. To this end, we analyze two-filter broadband imaging of 83

The distance to the Small Magellanic Cloud from multiband period-luminosity relations for classical Cepheids and its dependence on metallicity

EPJ Web of Conferences, 2017
We present a distance determination to the Small Magellanic Cloud (SMC) using optical and near-infrared photometry from OGLE and IRSF. Applying a multiband method to V, I, J, H and K OGLE and IRSF data, we measured the SMC true distance modulus and mean ...

Kinematics of young star clusters in the outer northeastern region of the Small Magellanic Cloud

Astronomy & Astrophysics
It has recently been suggested that the magnitude of the interaction between galaxies could be measured from the level of kinematic disturbance of their outer regions with respect to the innermost ones.

Molecular Clouds in the Large and Small Magellanic Clouds [PDF]

Highlights of Astronomy, 1989
To determine the distribution of molecular gas in the Large and Small Magellanic Clouds (LMC and SMC), we made complete surveys in the J=1-0 transition of CO, of the central 6°×6° and 3°×2° areas of the LMC and SMC, respectively. The observations were made with the 1.2m Columbia Telescope at Cerro Tololo, which provides and angular resolution of 8.8 ...

New 20-cm radio-continuum study of the small Magellanic cloud: Part I. Images [PDF]

Serbian Astronomical Journal, 2011
We present and discuss new high-sensitivity and resolution radiocontinuum images of the Small Magellanic Cloud (SMC) at λ=20 cm (ν=1.4 GHz). The new images were created by merging 20-cm radio-continuum archival data, from the Australian ...
