Spectroscopic characterization of Young Stellar Populations and their Feedback in NGC 5253
Svea Hernandez, Linda J. Smith, Valentina Abril-Melgarejo +1
We present the spectroscopic analysis of FUV observations taken with the Hubble Space Telescope (HST) Cosmic Origins Spectrograph (COS) targeting young massive clusters in the near…
Nebular C IV 1550 Imaging of the Metal-Poor Starburst Mrk 71: Direct Evidence of Catastrophic Cooling
M. S. Oey, Amit N. Sawant, Ashkbiz Danehkar +10
We use the Hubble Space Telescope ACS camera to obtain the first spatially resolved, nebular imaging in the light of C IV 1548,1551 by using the F150LP and F165LP filters. These ob…
Simultaneous Estimates of Star-cluster Age, Metallicity, Mass, and Extinction (SESAMME) I: Presenting an MCMC Approach to Spectral Stellar Population Fitting
Logan H. Jones, Svea Hernandez, Linda J. Smith +3
We present the first version release of SESAMME, a public, Python-based full spectrum fitting tool for Simultaneous Estimates of Star-cluster Age, Metallicity, Mass, and Extinction…
HST FUV Spectroscopy of Super Star Cluster A in the Green Pea Analog Mrk 71: Revealing the Presence of Very Massive Stars
Linda J. Smith, M. S. Oey, Svea Hernandez +10
Mrk 71 is a low metallicity (Z = 0.16 Z_sun) starburst region in the local dwarf galaxy NGC 2366, hosting two super star clusters (SSCs A and B), and is recognized as a Green Pea (…
A comprehensive metallicity analysis of J0332-3557: establishing a z ~ 4 anchor for direct gas metallicity and C/O abundance investigations
Annalisa Citro, Danielle A. Berg, Dawn K. Erb +4
We provide one of the most comprehensive metallicity studies at z 4 by analyzing the UV/optical HST photometry, and rest-frame VLT-FORS2 ultraviolet and VLT-XSHOOTER optical…
GN-z11 in context: possible signatures of globular cluster precursors at redshift 10
Peter Senchyna, Adele Plat, Daniel P. Stark +1
The first JWST spectroscopy of the luminous galaxy GN-z11 simultaneously both established its redshift at and revealed a rest-ultraviolet spectrum dominated by signatures…
Haro 11: Where is the Lyman continuum source?
Ryan P. Keenan, M. S. Oey, Anne E. Jaskot +1
Identifying the mechanism by which high energy Lyman continuum (LyC) photons escaped from early galaxies is one of the most pressing questions in cosmic evolution. Haro 11 is the b…
The Lyman break analogue Haro 11: spatially resolved chemodynamics with VLT FLAMES
B. L. James, Y. G. Tsamis, J. R. Walsh +2
Using VLT/FLAMES optical integral field unit observations, we present the first spatially resolved spectroscopic study of the well known blue compact galaxy Haro11, thought to be a…
Piecing together the puzzle of NGC 5253: abundances, kinematics and WR stars
M. S. Westmoquette, B. James, A. Monreal-Ibero +1
We present Gemini-S/GMOS-IFU optical spectroscopy of four regions near the centre of the nearby (3.8 Mpc) dwarf starburst galaxy NGC 5253. This galaxy is famous for hosting a radio…
The merging dwarf galaxy UM 448: chemodynamics of the ionized gas from VLT integral field spectroscopy
B. L. James, Y. G. Tsamis, M. J. Barlow +2
Using VLT/FLAMES optical IFU observations, we present a detailed study of UM 448, a nearby Blue Compact Galaxy (BCG) previously reported to have an anomalously high N/O abundance r…
Searching for an Intermediate Mass Black Hole in the Blue Compact Dwarf galaxy MRK 996
A. Georgakakis, Y. G. Tsamis, B. L. James +1
The possibility is explored that accretion on an intermediate mass black hole contributes to the ionisation of the interstellar medium of the Compact Blue Dwarf galaxy MRK996. Chan…
