ACA Meeting
November 07, Friday, 7:00 PM at
GRU The Public is invited!

Program: AGN = Active Galactic Nuclei
or "Radial Distances of Dust Sources in Low Ionization Broad Absorption Line Quasars"
Recent studies of very unique quasars (FeLoBALs) have shown that these objects have the potential
to shape both super massive black holes and their host galaxies.
Unfortunately, these objects tend to be extremely reddened due to dust.
This dust poses a large problem for FeLoBAL (and LoBAL) studies that attempt to determine the energies of these quasars.
Our search through objects in the Sloan Digital Sky Survey's vast database has uncovered a set of these FeLoBALs
that has shed light upon the locations of dust sources and potentially their nature.

Speaker: Jay Dunn,
2007 PhD GA State University, 2008-10 Post Doctoral Researcher, VA Polytechnic Institute and State University,
2010-11 Temporary Associate Professor, ASU (GRU) Since 2012 _________ at Perimeter College near Atlanta, teaching _____
Jay has mentored at least eight ? college students in research that lead to published papers.
His research focuses on Spectral Analysis of FeLoBAL Quasars and Ultraviolet Studies of Active Galactic Nuclei.

Jay presented a program to our club in 2011 about Outflows in Active Galactic Nuclei, and in 2012 Interstellar Medium.
He is a member of our club, and sometimes comes to help us on Astronomy Night &/or at SEED.
We are pleased to welcome him back again, and look forward to his contributions and keeping in touch.

Refreshments:
Lunar Observing after the meeting

Wear layered clothing.



ACA Dark Sky Star Gaze
November 22, Saturday, 7:00 PM at NMR-DSO
Moon rise/set: 0702/1749

The Andromeda Galaxy is rising high in the sky and should be visible naked-eye.
Etamin and Rastaban in the head of Draco are up there too.
Now is a good time to hear the Greek story of
The Princess and Perseus, and all the related Constellations.
Check out all those double stars we learned about last month.
Identify Menkar and Diphda, the head and tail of Cetus, in the SW.
Learn the names of the 4 stars that make the Great Square of Pegasus, learn Enif too.
They will take you many places.
The Pleiades have jewels to reveal. Taurus and the Hyades are full of discovery.

Wear layered clothing, hat.



Beginners to experts can benefit
from the abundance of knowledge, skill, and enthusiasm
at our local meetings and star parties.
Astronomy is not a simple sport. Get
help to get good.
