The Magellanic Stream and the Magellanic Cloud System [PDF]
Symposium - International Astronomical Union, 1999 A tidal model has been introduced to the triple system of the Galaxy, Large and Small Magellanic Clouds (the LMC and SMC hereafter) and successfully reproduced the Magellanic Stream (Murai and Fujimoto 1980; Lin and Lynden-Bell 1982; Gardiner et al. 1994; Gardiner and Noguchi 1995; Lin et al. 1995), a narrow band of diffuse atomic hydrogen gas emerging

The relation between radio flux density and ionizing ultra-violet flux for HII regions and supernova remnants in the Large Magellanic cloud [PDF]
Serbian Astronomical Journal, 2003 We present a comparison between the Parkes radio surveys (Filipović et al 1995) and Vacuum Ultra-Violet (VUV) surveys (Smith et al. 1987) of the Large Magellanic Clouds (LMC). We have found 72 sources in common in the LMC which are known HII regions (52)

CCD imagers for the Transiting Exoplanet Survey Satellite from benchtop to space environment
Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023 Abstract The Transiting Exoplanet Survey Satellite (TESS) is a Massachusetts Institute of Technology‐led NASA Explorer‐class mission planned to spend 2 years discovering transiting exoplanets by an all‐sky survey. The observatory contains four wide field‐of‐view camera systems for a total of 16.8 Megapixel, low‐noise, low‐power CCD detectors.

The Astrophysical Journal, 2023 The nature of molecular clouds and their statistical behavior in subsolar metallicity environments are not fully explored yet. We analyzed data from an unbiased CO ( J = 2–1) survey at the spatial resolution of ∼2 pc in the northern region of the Small ...

LRO‐LAMP Lunar South Pole Cold Traps: Assessment of H2O and Potential CO2 and NH3 Reserves
Journal of Geophysical Research: Planets, Volume 128, Issue 8, August 2023., 2023 Abstract Nighttime Lyman Alpha Mapping Project (LAMP) observations are used to investigate condensed volatiles at the south polar region of the Moon. This study incorporates LAMP data from the first ∼7 years of the mission and Diviner annual maximum temperatures to search for volatile signatures associated with H2O, NH3, and CO2. Other stable potential

Photometry and astrometry with JWST‐II: NIRCam distortion correction
Astronomische Nachrichten, Volume 344, Issue 3, March 2023., 2023 Abstract In preparation to make the most of our own planned James Webb Space Telescope investigations, we take advantage of publicly available calibration and early‐science observations to independently derive and test a geometric‐distortion solution for NIRCam detectors. Our solution is able to correct the distortion to better than ∼$$ \sim $$0.2 mas.

Ecology and Evolution, Volume 13, Issue 3, March 2023., 2023 Traditionally abiotic factors are considered the main drivers of biodiversity at macro‐scales, whereas biotic factors are considered important almost only at local scales. Modeling the distribution of 177 African bat species, we demonstrated the importance of considering biotic interactions in SDMs at macro‐scales regardless of the species’ ecology ...

Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023 Abstract Star‐forming and starburst galaxies (SBGs), which are well‐known cosmic‐ray (CR) reservoirs, are expected to emit gamma rays and neutrinos predominantly via hadronic collisions. In this work we analyze the 10‐year Fermi‐Low Energy Technique (LAT) spectral energy distributions of 13 nearby galaxies by means of a physical model that accounts for

Annals of the New York Academy of Sciences, Volume 1519, Issue 1, Page 7-19, January 2023., 2023 We review the long‐term climate variations during the last 540 million years (Phanerozoic Eon). We first summarize the geological and geochemical datasets available for reconstruction of long‐term climate variations. We then explore the main drivers of climate that appear to explain a large fraction of these climatic oscillations. The first is the long‐
