We have imaged the Circinus Galaxy in the near-infrared Fe ii] 1.64m and H 2 2.12m lines, and derived velocity maps for the emission. The morphologies are strikingly different , but the velocity maps are very similar and consistent with simple rotation. We also present new radio continuum maps at 3 cm and 6cm which show a partially resolved nucleus with a at spectral index. This suggests free-f...

Polymetallic complexes with covalently bridged metal centers that interact magnetically are important in the molecular magnetism field, binuclear compounds receiving special attention because they represent simplest type of multinuclear species centers. Herein, we report synthesis and properties two new FeII complexes, namely, {[Fe(abpt-TPE)(NCS)2]2(bpym)}·2MeOH·2MeCN (1) {[Fe(abpt-TPE)(NCS)2]2...

A family of terbium probes was synthesized and evaluated for the luminescence detection of copper and zinc in water at neutral pH. Each probe incorporates a terbium ion chelated by a macrocyclic polyaminocarboxylate and conjugated to either one, two, or three phenanthridine antennas via a diamine linker. All three probes, Tb-1Phen, Tb-2Phen, and Tb-3Phen, exhibit similar responses toward copper...

New species of amphibians are being reported at an astonishingly fast rate. These include some that have been known to the commercial pet trade for years but have not been formally described due to uncertain origin. The distinctive phenotype of “Pachytriton B” among the Chinese stout newts (also known as paddle-tailed newts) is one such example. Through examination of museum specimens, we locat...

Near-infrared (NIR) integral-field spectroscopy (IFS) of violent starburst environments at high spatial (and spectral) resolution has the potential to revolutionise our ideas regarding the local interactions between the newly-formed massive stars and the interstellar medium (ISM) of their host galaxies. To illustrate this point, I present NIR IFS analysis of the central starburst region of NGC ...
