Secular Evolution and the Formation of Pseudobulges in Disk Galaxies
Kormendy, John; Kennicutt, Robert C., Jr.
The Universe is in transition. At early times, galactic evolution was dominated by hierarchical clustering and merging, processes that are violent and rapid. In the far future, evolution will mostly be secular the slow rearrangement of energy and mass that results from interactions involving collective phenomena such as bars, oval disks, spiral st…
ISO Spectroscopy of Gas and Dust: From Molecular Clouds to Protoplanetary Disks
van Dishoeck, Ewine F.
Observations of interstellar gas-phase and solid-state species in the 2.4 200 m range obtained with the spectrometers on board the Infrared Space Observatory (ISO) are reviewed. Lines and bands caused by ices, polycyclic aromatic hydrocarbons, silicates, and gas-phase atoms and molecules (in particular H2, CO, H2O, OH, and CO…
Eros and Faint Red Galaxies
McCarthy, Patrick J.
This chapter reviews the properties of faint IR-selected field galaxies and the extremely red color-selected populations in particular. These populations are a mix of passively evolving stellar systems and heavily obscured star-forming galaxies. The star-forming component appears to constitute 20 50% of the population depending on the magnitude an…
My Cruise Through the World of Astronomy
Blaauw, Adriaan
I was born in 1914 in Amsterdam. I grew up there, filling my teenage years with activities as an amateur astronomer. I later studied at Leiden University and volunteered at Leiden Observatory. From 1938 to 1945, I was assistant at the Kapteyn Institute in Groningen, including during the war years 1940 1945, returning to Leiden in October 1945. Aft…
