Integral field spectroscopy of H2 and CO emission in IRAS 18276−1431: evidence for ongoing post-AGB mass-loss

We present K-band integral field spectroscopy of the bipolar post-AGB object IRAS 18276-1431 (OH 17.7-2.0) using SINFONI on the VLT. This allows us to image both the continuum and molecular features in this object from 1.95-2.45{\mu}m with a spatial

VLT/near-infrared integral field spectrometer observations of molecular hydrogen lines in the knots of the planetary nebula NGC 7293 (the Helix Nebula)

Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots may reveal the processes d

Near-infrared polarimetry and modelling of the dusty young planetary nebula IRAS 19306+1407

Autor: K. T. E. Lowe, Tim Gledhill

Publikováno v: Monthly Notices of the Royal Astronomical Society. 374:176-186

We present near-infrared polarimetric images of the dusty circumstellar envelope (CSE) of IRAS 19306+1407, acquired at the United Kingdom Infrared Telescope (UKIRT) using the UKIRT 1-5 µm Imager Spectrometer (UIST) in conjunction with the half-wavep

Near-infrared imaging polarimetry of dusty young stars

Autor: M. J. Barlow, Tim Gledhill, K. T. E. Lowe, Antonio Hales

Publikováno v: Monthly Notices of the Royal Astronomical Society. 365:1348-1356

We have carried out JHK polarimetric observations of eleven dusty young stars, by using the polarimeter module IRPOL2 with the near-IR camera UIST on the 3.8-m United Kingdom Infrared Telescope (UKIRT). Our sample targeted systems for which UKIRT-res

Blood oxygen-binding characteristics of bigeye tuna ( Thunnus obesus ), a high-energy-demand teleost that is tolerant of low ambient oxygen

Autor: T. E. Lowe, Richard W. Brill, K. L. Cousins

Publikováno v: Marine Biology. 136:1087-1098

We found blood from bigeye tuna (Thunnus obesus) to have a significantly higher O2 affinity than blood from other tunas. Its P50 (partial pressure of oxygen, PO2 required to reach 50% saturation) was 1.6 to 2.0 kPa (12 to 15 mmHg) when equilibrated w

Responses of the red blood cells from two high-energy-demand teleosts, yellowfin tuna ( Thunnus albacares ) and skipjack tuna ( Katsuwonus pelamis ), to catecholamines

Autor: K. L. Cousins, T. E. Lowe, Richard W. Brill

Publikováno v: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology. 168:405-418

In fishes, catecholamines increase red blood cell intracellular pH through stimulation of a sodium/proton (Na+/H+) antiporter. This response can counteract potential reductions in blood O2 carrying capacity (due to Bohr and Root effects) when plasma

Exercise challenge in Antarctic fishes: do haematology and muscle metabolite levels limit swimming performance?

Autor: T. E. Lowe, Rufus M. G. Wells

Publikováno v: Polar Biology. 17:211-218

Burst swimming increased haematocrit (partly from erythrocyte swelling) in the cryopelagic nototheniid Pagothenia borchgrevinki, but not in the benthic species Trematomus bernacchii. Erythrocyte nucleotides, which regulate haemoglobin-oxygen affinity
