The disruption of the Magellanic Stream [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractWe present evidence that the accretion of warm gas onto the Galaxy today is at least as important as cold gas accretion. For more than a decade, the source of the bright Hα emission (up to 750 mR†) along the Magellanic Stream has remained a mystery.

The Era of Kilometer‐Scale Neutrino Detectors
Advances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013 Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer‐scale neutrino detectors were required. The first such instrument, IceCube, transforms a cubic kilometer of deep and ultra‐transparent Antarctic ice into a particle detector.

Metal Abundances in the Magellanic Stream
The Astronomical Journal, 2000 We report on the first metallicity determination for gas in the Magellanic Stream, using archival HST GHRS data for the background targets Fairall 9, III Zw 2, and NGC 7469. For Fairall 9, using two subsequent HST revisits and new Parkes Multibeam Narrowband observations, we have unequivocally detected the MSI HI component of the Stream (near its head)

The origin of the microlensing events observed towards the LMC and the stellar counterpart of the Magellanic stream [PDF]
, 2012 We introduce a novel theoretical model to explain the long-standing puzzle of the nature of the microlensing events reported towards the Large Magellanic Cloud (LMC) by the MACHO and OGLE collaborations.

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).

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 Core‐collapse supernovae are dramatic explosions marking the catastrophic end of massive stars. The only means to get direct information about the supernova engine is from observations of neutrinos emitted by the forming neutron star, and through gravitational waves which are produced when the hydrodynamic flow or the neutrino flux is not perfectly ...

Galactic Cannibalism: The Origin of the Magellanic Stream [PDF]
, 2002 We are in a privileged location in the Universe which allows us to observe galactic interactions from close range---the merger of our two nearest dwarf satellite galaxies, the LMC and SMC. It is important to understand the local merger process before we can have confidence in understanding mergers at high redshift.

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.

Pulsar‐Driven Jets in Supernovae, Gamma‐Ray Bursts, and the Universe
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 The bipolarity of Supernova 1987A can be understood through its very early light curve from the CTIO 0.4 m telescope and IUE FES and following speckle observations of the “Mystery Spot”. These indicate a beam/jet of light/particles, with initial collimation factors >104 and velocities >0.95 c, involving up to 10−5 M⊙ interacting with circumstellar ...

The Truncated Circumgalactic Medium of the Large Magellanic Cloud
The Astrophysical Journal LettersThe Large Magellanic Cloud (LMC) is the nearest massive galaxy to the Milky Way (MW). Its circumgalactic medium (CGM) is complex and multiphase, containing both stripped H i structures like the Magellanic Stream and Bridge and a diffuse warm corona seen ...
