Hunting for the Dark Matter Wake Induced by the Large Magellanic Cloud [PDF]

Astrophysical Journal, 2019
Satellite galaxies are predicted to generate gravitational density wakes as they orbit within the dark matter (DM) halos of their hosts, causing their orbits to decay over time. The recent infall of the Milky Way’s (MW) most massive satellite galaxy, the

The Large Magellanic Cloud stellar content with SMASH [PDF]

Astronomy & Astrophysics, 2020
The Large Magellanic Cloud (LMC) is the closest and most studied example of an irregular galaxy. Among its principal defining morphological features, its off-centred bar and single spiral arm stand out, defining a whole family of galaxies known as the ...

Chemical Composition of RM_1-390 - Large Magellanic Cloud Red Supergiant [PDF]

Journal of Astronomy and Space Sciences, 2017
A high resolution spectroscopic observation of the red supergiant star RM_1-390 in the Large Magellanic Cloud was made from a 3.6 m telescope at the European Southern Observatory. Spectral resolving power was R=20,000, with a signal-to-noise ratio S/N >

The Large Magellanic Cloud with the Cherenkov Telescope Array [PDF]

EPJ Web of Conferences, 2019
The Large Magellanic Cloud (LMC) is a spiral galaxy, satellite of the Milky way with a high star formation activity. It represents a unique laboratory for studying an extended and spatially resolved star-forming galaxy through gamma-ray observatories ...

The Wolf-Rayet binaries of the nitrogen sequence in the Large Magellanic Cloud [PDF]

Astronomy & Astrophysics, 2019
Context. Massive Wolf–Rayet (WR) stars dominate the radiative and mechanical energy budget of galaxies and probe a critical phase in the evolution of massive stars prior to core collapse.

The influence of Sagittarius and the Large Magellanic Cloud on the stellar disc of the Milky Way Galaxy [PDF]

Monthly notices of the Royal Astronomical Society, 2017
We present N-body simulations of a Sagittarius-like dwarf spheroidal galaxy (Sgr) that follow its orbit about the Milky Way (MW) since its first crossing of the Galaxy's virial radius to the present day.

Optical spectra of radio planetary nebulae in the large Magellanic Cloud [PDF]

Serbian Astronomical Journal, 2008
We present 11 spectra from 12 candidate radio sources co-identified with known planetary nebulae (PNe) in the Large Magellanic Cloud (LMC). Originally found in Australia Telescope Compact Array (ATCA) LMC surveys at 1.4, 4.8 and 8.64 GHz and confirmed by

An ALMA View of Molecular Filaments in the Large Magellanic Cloud. II. An Early Stage of High-mass Star Formation Embedded at Colliding Clouds in N159W-South [PDF]

Astrophysical Journal, 2018
We have conducted ALMA CO isotopes and 1.3 mm continuum observations toward filamentary molecular clouds of the N159W-South region in the Large Magellanic Cloud with an angular resolution of ∼0.″25 (∼0.07 pc). Although the previous lower-resolution (∼1″)

MACHO 311.37557.169: A VY Scl star

Astronomische Nachrichten, Volume 341, Issue 3, Page 283-290, March 2020., 2020
Abstract Optical surveys, such as the MACHO project, often uncover variable stars whose classification requires follow‐up observations by other instruments. We performed X‐ray spectroscopy and photometry of the unusual variable star MACHO 311.37557.169 with XMM‐Newton in April 2018, supplemented by archival X‐ray and optical spectrographic data.

An Independent Determination of the Distance to Supernova SN 1987A by Means of the Light Echo AT 2019xis

The Astrophysical Journal Letters, 2023
Accurate distance determination to astrophysical objects is essential for the understanding of their intrinsic brightness and size. The distance to SN 1987A has been previously measured by the expanding photosphere method and by using the angular size of
