Roman Early-Definition Astrophysics Survey Opportunity: Galactic Roman Infrared Plane Survey (GRIPS)
Roberta Paladini, Catherine Zucker, Robert Benjamin +67
A wide-field near-infrared survey of the Galactic disk and bulge/bar(s) is supported by a large representation of the community of Galactic astronomers. The combination of sensitiv…
FSR 1776: a new globular cluster in the Galactic bulge?
B. Dias, T. Palma, D. Minniti +6
(ABRIDGED) Recent near-IR surveys have uncovered a plethora of new globular cluster (GC) candidates towards the Milky Way bulge. These new candidates need to be confirmed as real G…
The role of the diffuse ionized gas in metallicity calibrations
N. Vale Asari
Estimates of gas-phase abundances based on strong-line methods have been calibrated for H~{\scshape ii} regions. Those methods ignore any contribution from the diffuse ionized gas…
A quick start guide to BOND: Bayesian Oxygen and Nitrogen abundance Determinations in H II regions using strong and semistrong lines
N. Vale Asari, G. Stasińska, C. Morisset +1
We present a quick-start guide to BOND, a statistical method to derive oxygen and nitrogen abundances in H II regions. BOND compares a set of carefully selected strong and semistro…
Star-powered LINERs in the Sloan Digital Sky Survey
N. Vale Asari, G. Stasinska, R. Cid Fernandes +5
Galaxies are usually classified as star forming or active by using diagnostic diagrams, such as [N II]/Halpha vs. [O III]/Hbeta. Active galaxies are further classified into Seyfert…
The starburst-AGN disconnection
R. Cid Fernandes, M. Schlickmann, G. Stasinska +5
Optical studies of starbursts, AGN and their connections usually leave out galaxies whose emission lines are too weak to warrant reliable measurement and classification. Yet, weak…
