The Metallicities of Five Small High-velocity Clouds
The Astrophysical JournalHigh-velocity clouds (HVCs) are multiphase gas structures whose velocities (∣ v _LSR ∣ ≥ 100 km s ^−1 ) are too high to be explained by Galactic disk rotation.

N-body Simulations of the Small Magellanic Cloud and the Magellanic Stream [PDF]
, 1995 An extensive set of N-body simulations has been carried out on the gravitational interaction of the Small Magellanic Cloud (SMC) with the Galaxy and the Large Magellanic Cloud (LMC). The SMC is assumed to have been a barred galaxy with a disc-to-halo mass ratio of unity before interaction and modelled by a large number of self-gravitating particles ...

Beyond Accretion Limits: The Rise of Pulsating Gems
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).

Binarity among Cepheids in the Magellanic Clouds [PDF]
MNRAS 426, 3148-3153 (2012), 2012 Spectroscopic binarity of the Cepheid variable HV914 in the Large Magellanic Cloud is pointed out from the published radial velocity observational data. The list of known binaries among Cepheid type variable stars in the Magellanic Clouds is published in tabular form.

New quasars behind the Magellanic Clouds. Spectroscopic confirmation of near-infrared selected candidates [PDF]
, 2015 Context. Quasi-stellar objects (quasars) located behind nearby galaxies provide an excellent absolute reference system for astrometric studies, but they are difficult to identify because of fore- and background contamination.

Spectral Studies of Super‐Eddington Accreting Neutron Stars in the Magellanic Clouds
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT Major outbursts of BeXRBs offer a unique laboratory for studying accretion onto magnetized neutron stars (NSs) over a large dynamic range. The accreting material is entrained from the accretion disk by the strong magnetic field, and then channeled onto the NS, forming a so‐called accretion column (AC).

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.

A history of the Magellanic Clouds and the European exploration of the Southern Hemisphere [PDF]
, 2020 The Magellanic Clouds were known before Magellan's voyage exactly 500 years ago, and were not given that name by Magellan himself or his chronicler Antonio Pigafetta. They were, of course, already known by local populations in South America, such as the Mapuche and Tupi-Guaranis. The Portuguese called them Clouds of the Cape, and scientific circles had

Spatial distribution of stellar populations in the Magellanic Clouds: Implementation to Gaia
, 2011 The main goal of our project is to investigate the spatial distribution of different stellar populations in the Magellanic Clouds. The results from modelling the Magellanic Clouds can be useful, among others, for simulations during the Gaia mission ...
