INTEGRAL observations of the Small Magellanic Cloud

, 2007
The first INTEGRAL observations of the Small Magellanic Cloud (carried out in 2003) are reported in which two sources are clearly detected. The first source, SMC X-1, shows a hard X-ray eclipse and measurements of its pulse period indicate a continuation

Surveying the Agents of Galaxy Evolution in the Tidally Stripped, Low Metallicity Small Magellanic Cloud (SAGE-SMC). I. Overview [PDF]

, 2011
The Small Magellanic Cloud (SMC) provides a unique laboratory for the study of the lifecycle of dust given its low metallicity (~1/5 solar) and relative proximity (~60 kpc).

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).

Mapping the Distorted Dark Matter Distribution of the LMC–SMC System Prior to Milky Way Infall with Basis Function Expansions

The Astrophysical Journal
The SMC orbits within the LMC’s dark matter (DM) halo in a ∼1:10 mass-ratio encounter. The LMC–Milky Way (MW) interaction is also ∼1:10, and is expected to perturb the MW’s DM distribution.

Optical spectroscopy of 20 Be/X-ray Binaries in the Small Magellanic Cloud

, 2009
We present a large sample (20 in total) of optical spectra of Small Magellanic Cloud (SMC) High-Mass X-ray Binaries obtained with the 2dF spectrograph at the Anglo-Australian Telescope.

Dust emission at 8-mic and 24-mic as Diagnostics of HII Region Radiative Transfer [PDF]

, 2017
We use the Spitzer SAGE survey of the Magellanic Clouds to evaluate the relationship between the 8-mic PAH emission, 24-mic hot dust emission, and HII region radiative transfer.

Principal sensory experiences of forest visitors in four countries, for evidence‐based nature therapy

People and Nature, Volume 6, Issue 6, Page 2480-2493, December 2024.
Abstract To advance the theoretical and practical underpinnings for nature therapies, i.e. nature exposure as a means to improve mental health, we compared the most memorable sensory experiences reported by forest tourists in Australia, Chile, China and Japan. Sensory experiences are a fundamental driver of the psychological effects of nature exposure.

The Metallicities of Five Small High-velocity Clouds

The Astrophysical Journal
High-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.

A new search for R Coronae Borealis stars in the SMC

EPJ Web of Conferences, 2017
R Coronae Borealis (RCB) stars are rare, and their evolutionary origin is not well understood. Since they are obscured due to formation of carbon dust around the star during their mass loss events, RCB stars can be classified as self-eclipsing variable ...

The Detection of Hot Molecular Cores in the Small Magellanic Cloud

The Astrophysical Journal Letters, 2023
We report the first detection of hot molecular cores in the Small Magellanic Cloud (SMC), a nearby dwarf galaxy with 0.2 solar metallicity. We observed two high-mass young stellar objects in the SMC with the Atacama Large Millimeter/submillimeter Array ...
