Sentences with phrase «nuclear region»

According to Kool the results coming from SUNBIRD reveal that their new approach provides a powerful tool for uncovering core - collapse supernova in nuclear regions of galaxies.

When compared to the total sample of LIRG CCSNe discovered in the near - IR and optical, we show that our method is singularly effective in uncovering CCSNe in nuclear regions and we conclude that the majority of CCSNe exploding in LIRGs are not detected as a result of dust obscuration and poor spatial resolution.

Remarkably, these supernovae were spotted as close as 600 light years from the bright nuclear regions of these galaxies — despite being at least 150 million light years from the Earth.

Such a shortfall is particularly prominent in luminous infrared galaxies (LIRGs), which have high star formation (and thus CCSN) rates and host bright and crowded nuclear regions, where large extinctions and reduced search detection efficiency likely lead to a significant fraction of CCSNe remaining undiscovered.

We present the first results of project SUNBIRD (Supernovae UNmasked By InfraRed Detection), where we aim to uncover CCSNe that otherwise would remain hidden in the complex nuclear regions of LIRGs, and in this way improve the constraints on the fraction that is missed by optical seeing - limited surveys.

Right inset: e-MERLIN maps of the nuclear region of NGC 5195 at 1.4 GHz (left) and 5 GHz (right).

Preliminary data indicate prominent accumulation of aluminum within the nuclear region and perikaryal cytoplasm of NFT - bearing hippocampal neurons, regardless of the underlying neurological diagnosis.

Although this study focused on plastomes and utilized the popular Illumina sequencing platform, Uribe - Convers explains,» [t] his can easily be expanded to mitochondrial and nuclear regions, and can be used in combination with any next - generation sequencing platform.

Tod R. Lauer of the National Optical Astronomy Observatory in Tucson, Ariz., assembled this image of the nuclear region by taking several blue and ultraviolet light exposures of the nucleus with Hubble's Advanced Camera for Surveys high - resolution channel during September 2005 and February 2006, each time slightly moving the telescope to change how the camera sampled the region.

Kool adds, «The supernova rate problem can be resolved using the unique multi-conjugate adaptive optics capability provided by Gemini, which allows us to achieve the highest spatial resolution in order to probe very close to the nuclear regions of galaxies.»

We observe in the near - infrared 2.15 µm Ks - band, which is less affected by dust extinction compared to the optical, using the multi-conjugate adaptive optics imager GeMS / GSAOI on Gemini South, allowing us to achieve a spatial resolution that lets us probe close in to the nuclear regions.

The nuclear region of M87 is known as an «active galactic nucleus» due to its brightness in visible, x-ray, radio, and other wavelengths of light.
