ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets
Finding Characterizing Exoplanets
2014/12/22
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 – 400 ìm wavelength range, a far-IR interferometer will revolutionize our understanding of planetary system format...
CIRCUMSTELLAR STRUCTURE AROUND EVOLVED STARS IN THE CYGNUS-X STAR FORMATION REGION
Cygnus-X star MIPS IRAC
2014/12/22
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the Cygnus-X star forming...
THE CALIBRATION OF MONOCHROMATIC FAR-INFRARED STAR FORMATION RATE INDICATORS
star formation starburst galaxies
2014/12/20
Spitzer data at 24, 70, and 160 μm and ground-based Hα images are analyzed for a sample of 189 nearby star-forming and starburst galaxies to investigate whether reliable star formation rate (SFR) indi...
If we are to develop a comprehensive and predictive theory of galaxy formation and evolution, it is essential that we obtain an accurate assessment of how and when galaxies assemble their stellar popu...
The spatial distribution of star formation in the solar neighbourhood: do all stars form in dense clusters?
low-mass neighbours Spitzer Space Telescope
2014/12/20
We present a global study of low-mass, young stellar object (YSO) surface densities (ヒ) in nearby (<500 >pc) star-forming regions based on a comprehensive collection of Spitzer Space Telescope surveys...
100 m and 160 m emission as resolved star–formation rate estimators in M33 (HERM33ES
di use emission galaxies
2014/12/20
Context. Over the past few years several studies have provided estimates of the SFR (star–formation rate) or the total infrared luminosity from just one infrared band. However these relations are gene...
We present new images and photometry of the massive star-forming complex Cygnus X obtained with the Infrared Array Camera (IRAC) and the Multiband Imaging Photometer for Spitzer (MIPS) on board the Sp...
PROGRESSIVE STAR FORMATION IN THE YOUNG GALACTIC SUPER STAR CLUSTER NGC 3603
star formation history
2014/12/20
Early Release Science observations of the cluster NGC 3603 with the WFC3 on the refurbished Hubble Space Telescope allow us to study its recent star formation history. Our analysis focuses on stars wi...

550 Million Year Old Fossils Provide New Clues Fossil Formation
2014/12/30
COLUMBIA, Mo. – A new study from University of Missouri and Virginia Tech researchers is challenging accepted ideas about how ancient soft-bodied organisms become part of the fossil record. ...

simulated using reduced (i.e. simplified) models.
Characterization and phosphorylation of an MPM-2 reactive sperm protein complex involved in zygotic aster formation
Sperm tubes egg quality microtubules female pronucleus male pronucleus fertilized egg triplet protein
2014/12/11
The zygotic centrosome, contributed by the sperm, forms an array of microtubules that spread throughout the ooplasm. These microtubules are used by the female pronucleus to come into juxtaposition wit...
Formation and plasticity of glutamatergic synapses: Characterization of the roles of beta-amyloid precursor protein, scribble, and wingless at the Drosophila neuromuscular junction
Neurons circuit static core
2014/12/11
The flow of information through neuronal circuits relies on the ability of neurons to form synaptic connections with specific temporal and spatial properties. These properties are not static but have ...

Centromere chromosomes cell division protein chromosome axis of fiber
2014/12/11
Centromeres are the site on a chromosome that allows for proper chromosome segregation during cell division. The kinetochore, a DNA-protein complex that forms at the centromere, attaches the chromosom...
