Formation of dense filaments induced by runaway supermassive black holes

A narrow linear object extending ~60kpc from the centre of a galaxy at redshift z ~ 1 has been recently discovered and interpreted as a shocked gas filament forming stars. The host galaxy presents an irregular morphology, implying recent merger events. Supposing that each of the progenitor galaxies has a...

Probing quasar proximity zones with Lyman-alpha emission: Can we guess quasar’s age?

Ryuichiro Hada

Ohio Stsate University

We present a theoretical framework for linking quasar properties, such as quasar age, to the surrounding Ly α emission intensity. In particular, we focus on a method for mapping the large-scale structure of Ly α emission intensity with galaxy spectra from wide-field spectroscopic surveys, e.g. the Subaru Prime Focus Spectrograph...
