Powerful extragalactic radio sources comprise two extended regions containing magnetic
field and synchrotron-emitting relativistic electrons, each linked by a jet to a central compact …

▪ Abstract Galactic winds are the primary mechanism by which energy and metals are
recycled in galaxies and are deposited into the intergalactic medium. New observations are …

Cooling functions for low-density astrophysical plasmas ADS Classic is now deprecated. It
will be completely retired in October 2019. This page will automatically redirect to the new …

Much of the interstellar medium in disk galaxies is in the form of neutral atomic hydrogen, H
I. This gas can be in thermal equilibrium at relatively low temperatures, T≲ 300 K (the cold …

This paper proposes a simple, empirically derived, unifying structure for the inner regions of
quasars. This structure is constructed to explain the broad absorption line regions (BALRs) …

Molecular tori in Seyfert galaxies - Feeding the monster and hiding it ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

We present results of calculations using the XSTAR version 2 computer code. This code is
loosely based on the XSTAR version 1 code, which has been available for public use for …

X rays emitted in the inner part of an accretion disk system can heat the surface of the disk
farther out, producing a corona and possibly driving off a strong wind. The dynamics of …

We present the first results from the ongoing, intensive, multiwavelength monitoring program
of the luminous Seyfert 1 galaxy Mrk 817. While this active galactic nucleus was, in part …

▪ Abstract Blueshifted absorption lines in the UV and X-ray spectra of active galaxies reveal
the presence of massive outflows of ionized gas from their nuclei. The “intrinsic” UV and X …
