Ecology and Evolution, Volume 14, Issue 2, February 2024.Some white‐tailed deer populations are migratory in locations with severe and chronic seasonal resource limitations, but biological justification for such behaviors is lacking at lower latitudes. We document migratory behavior termed the "mobile" movement strategy in 33% of adult male deer in a low‐latitude system void of such environmental pressures ...

In Pursuit of the Least Luminous Galaxies
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass spectrum, and clustering scale of dark matter.

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 ...

The Relevance of Dynamical Friction for the MW/LMC/SMC Triple System
UniverseSimulations of structure formation in the standard cold dark matter cosmological model quantify the dark matter halos of galaxies. Taking into account dynamical friction between dark matter halos, we investigate the past orbital dynamical evolution of ...

Monitoring of X‐Ray Sources in the Optical Spectral Region
Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 We review current results and perspectives of the photometric monitoring of the optical counterparts of X‐ray sources of various kinds (binary X‐ray sources (cataclysmic variables and low‐mass X‐ray binaries, supersoft X‐ray sources, microquasars), gamma‐ray bursts).

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.

The detection of an older population in the Magellanic Bridge [PDF]
, 2012 The Magellanic system comprises the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the less frequently observed Magellanic Bridge and Magellanic Stream. The Bridge is traced by neutral gas and has an observed stellar component, while the Stream consists of gas only, with no observed stellar counterpart to date.

The Multiple Extended Tidal Tails of NGC 288
The Astrophysical JournalUsing photometry and proper motions from Pan-STARRS, DECaLS, and Gaia Data Release 3, we detect a ∼35°–70° long trailing stellar debris stream associated with the globular cluster NGC 288.

The Astronomical JournalCold neutral hydrogen (H i ) is a crucial precursor for molecular gas formation and can be studied via H i absorption. This study investigates H i absorption in low column density regions of the Small and Large Magellanic Clouds (SMC and LMC) using the ...

Revealing the Ionization Properties of the Magellanic Stream using Optical Emission [PDF]
, 2017 The Magellanic Stream, a gaseous tail that trails behind the Magellanic Clouds, could replenish the Milky Way with a tremendous amount of gas if it reaches the Galactic disk before it evaporates into the halo. To determine how the Magellanic Stream's properties change along its length, we have conducted an observational study of the H-alpha emission ...
