Discovery of Newly Formed Broad Absorption Lines in a Radio-Loud Quasar

Feng Ma

We report a serendipitous discovery of broad absorption lines that were newly formed in the spectrum of the high-redshift, luminous radio-loud quasar TEX 1726 + 344, in a time inte…

Spin--Down Power in Astrophysics

Feng Ma

While the accretion power in astrophysics has been studied in many astronomical environments, the ``spin--down power'' is often neglected. In this essay I demonstrate that the spin…

Discovery of Hidden Blazars

Feng Ma, Beverley J. Wills

A blazar is believed to exist in every radio-loud quasar. This is expected in a unified scheme where the differences in both optical and radio observations of radio-loud quasars ar…

Hidden Blazars and Emission Line Variability of High Redshift Quasars

Feng Ma

We have carried out a survey to search for hidden blazars in a sample of radio-loud quasars. The idea is based on our prediction that we should be able to see large CIV…

Possible Signatures of Quark-Hadron Phase Transitions inside Neutron Stars

Feng Ma

The spin-down power of an isolated neutron star can drive its central density increase and overall structural changes, and trigger a quark-hadron phase transition. A series of obse…

Does Every Quasar Harbor A Blazar?

Feng Ma, Beverley J. Wills

Assuming there is a blazar type continuum in every radio-loud quasar, we find that the free-free heating due to the beamed infrared continuum can greatly enhance collisionally exci…

Super-Giant Glitches and Quark Stars: Sources of Gamma Ray Bursts?

Feng Ma, Bingrong Xie

When a spinning-down neutron star undergoes a phase transition that produces quark matter in its core, a Super-Giant Glitch of the order occurs on time scales from…
