LURID WORLD. “A small but significant fraction of submm galaxies appear to be associated with EROs at bright magnitudes.” (ERO = extremely red objects). https://lnkd.in/dAkZ_ejH View in LinkedIn

DEATH OF STARS. “Gamma-ray burst (GRB) host galaxies. An interesting new development is the idea that if GRBs are likely to be associated with the deaths of massive stars, then the rate of GRBs and the global high-mass star-formation rate should be linked.” https://lnkd.in/dAkZ_ejH View in LinkedIn

RECENTLY DESCRIBED. “As soon as the first submm galaxies were detected in 1997, it was clear that they made a significant contribution to the luminosity density in the high-redshift Universe, subject to the plausible assumptions that their SEDs were similar to those of luminous low-redshift dusty galaxies, and that their redshifts were not typically less than about z = 0.5.” (SED = spectral energy distribution). https://lnkd.in/dAkZ_ejH View in LinkedIn

INTER-RELATED. “It is not possible to separate the modeling of the evolution of the population of submm galaxies fully from studies of the nature of the galaxies themselves.” https://lnkd.in/dAkZ_ejH View in LinkedIn

COSMIC TIME. “Their luminosities and masses demand that the submm-luminous phase be short-lived as compared with the age of the Universe.” https://lnkd.in/dAkZ_ejH View in LinkedIn

THIS CONCLUDES the section on sub-millimeter wavelength galaxies. It amply illustrates how little we know about the universe around us. We are essentially still in the dark ages, with primitive tools and rather little data, despite the remarkable advances in very recent years. We are still just sitting around the camp fire looking up at the night sky. https://lnkd.in/dAkZ_ejH View in LinkedIn

THE BODY IMPACTS MEMORY. “Mental representations need to be grounded in perception and action, as they cannot be a “free-floating system of symbols”. Memories are not abstract items neatly stored in our brains simply because they emerge from proximal sensory projections that include sensorimotor elements in their representations.” https://lnkd.in/dx_WeJt4 View in LinkedIn

FRAGMENT FROM NATURE features the commonly referred to “butterfly effect” from the mindset of a cardiologist, first author, James N. Weiss MD, of the Cardiovascular Research Laboratory and the Department of Medicine, UCLA School of Medicine, Los Angeles. We cite this phenomenon in our cultural experience often without much understanding of it. It is, it seems, everywhere. https://lnkd.in/dGJFZZDC View in LinkedIn
