Galaxy 0421 +040p06: an Active Spiral (?) Galaxy with Extended
The infrared bright galaxy 0421 +040P06 detected by IRAS at 25 and 60 μm has been studied at optical, infrared, and radio wavelengths. It is a luminous galaxy with apparent spiral structure emitting 4 x 1037 W (1 x 1011 L 0 ) from far-infrared to optical wavelengths, assuming H 0 = 75 km s1 Mpc1• Optical spectroscopy reveals a Seyfert 2 emission-line spectrum, making 0421 +040P06 the first acti...
متن کاملActive Galaxy Unification
Most bright galaxies are spirals, like our own, and in the nearby well-studied cases they reveal the beautiful and intricate grand-design spiral patterns that are both familiar and appealing (e.g., Sandage & Tammann 1981). At the centre of a few out of every hundred spirals there is also an extremely bright point of light. This point can be so bright that it can outshine the entire stellar outp...
متن کاملActive Learning Applied to Patient-Adaptive Heartbeat Classification
While clinicians can accurately identify different types of heartbeats in electrocardiograms (ECGs) from different patients, researchers have had limited success in applying supervised machine learning to the same task. The problem is made challenging by the variety of tasks, interand intra-patient differences, an often severe class imbalance, and the high cost of getting cardiologists to label...
متن کاملVascular endothelial ageing, heartbeat after heartbeat.
The vascular endothelium starts to age at the first heartbeat. There is no longer a need to demonstrate that an increased resting heart rate--above 70 b.p.m.--is associated with the onset of cardiovascular events and reduces lifespan in humans. Each cardiac cycle imposes a mechanical constraint on the arteries, and we would like to propose that this mechanical stress damages the vascular endoth...
متن کاملA submillimetre-selected, ultraluminous, active galaxy
We present a detailed study of SMM02399−0136, an ultraluminous, active galaxy selected from a sub-mm survey of the distant Universe. This object is the brightest source in the fields of four rich, lensing clusters, with a total area of ∼20 arcmin, that we have mapped with a sensitivity better than 2mJy beam at 850μm. We identify a compact optical counterpart with an apparent magnitude of B ∼ 23...
