Abstract A series of population models are designed to explore the star formation history of gas-rich, low surface brightness (LSB) galaxies. LSB galaxies are unique in having properties of very blue colors, low Hα emission and high gas fractions that indicated a history of constant star formation (versus the declining star formation models used for most spirals and irregulars). The model simulations use an evolving multi-metallicity composite population that follows a chemical enrichment… 
Stellar Populations and the Star Formation Histories of LSB Galaxies: V. WFC3 Color-Magnitude Diagrams
We present WFC3 observations of three low surface brightness (LSB) galaxies from the Schombert et. al LSB catalog that are within 11 Mpc of the Milky Way. Deep imaging at F336W, F555W and F814W allow
A recent starbust in the low surface brightness galaxy UGC 628
We present the star-formation history of the low surface brightness (LSB) galaxy UGC 628 as part of the MUSCEL program (MUltiwavelength observations of the Structure, Chemistry, and Evolution of LSB
Anomalous Stellar Populations in Low-surface-brightness Galaxies
We present new Hubble Space Telescope WFC3 near-IR observations of the color–magnitude diagrams (CMDs) in two low-surface-brightness galaxies, F575-3 and F615-1, notable for having no current star
From spirals to lenticulars: Evidence from the rotation curves and mass models of three early-type galaxies
Rotation curves have traditionally been difficult to trace for early-type galaxies (ETGs) because they often lack a high-density disk of cold gas as in late-type galaxies (LTGs). We derive rotation
The Star Forming Main Sequence of Dwarf Low Surface Brightness Galaxies
We explore the star forming properties of late type, low surface brightness (LSB) galaxies. The star forming main sequence (SFR-$M_*$) of LSB dwarfs has a steep slope, indistinguishable from unity
Peak star formation efficiency and no missing baryons in massive spirals
It is commonly believed that galaxies use, throughout Hubble time, a very small fraction of the baryons associated with their dark matter halos to form stars. This so-called low star formation
The properties of the Malin 1 galaxy giant disk - A panchromatic view from the NGVS and GUViCS surveys
Context. Low surface brightness galaxies (LSBGs) represent a significant percentage of local galaxies but their formation and evolution remain elusive. They may hold crucial information for our
Stellar Mass-to-light Ratios: Composite Bulge+Disk Models and the Baryonic Tully–Fisher Relation
We present stellar population models to calculate the mass-to-light ratio (ϒ*) based on galaxies’ colors ranging from GALEX far-UV to Spitzer IRAC1 at 3.6 μm. We present a new composite bulge+disk ϒ*
Comparison of Modeling SPARC spiral galaxies’ rotation curves: halo models vs. MOND
The tension between luminous matter and dynamical matter has long been an interesting and controversial topic in the investigation of galaxies. This is particularly true when we study spiral galaxies
Rotation curves of galaxies and the stellar mass-to-light ratio
Mass models of a sample of 171 low- and high-surface brightness galaxies are presented in the context of the cold dark matter (CDM) theory using the NFW dark matter halo density distribution to


Stellar Populations and the Star Formation Histories of LSB Galaxies—Part I: Optical and Hα Imaging
This paper presents optical and Hα imaging for a large sample of LSB galaxies selected from the PSS-II catalogs (Schombert et al., 1992). As noted in previous work, LSB galaxies span a range of
Stellar Populations and the Star Formation Histories of LSB Galaxies: II. HII Regions
The luminosities, colors and H\alpha\ emission for 429 HII regions in 54 LSB galaxies are presented. While the number of HII regions per galaxy is lower in LSB galaxies compared to star-forming
The stellar populations of spiral galaxies
ABSTRA C T We have used a large sample of low-inclination spiral galaxies with radially resolved optical and near-infrared photometry to investigate trends in star formation history with radius as a
The different star formation histories of blue and red spiral and elliptical galaxies
We study the spectral properties of intermediate mass galaxies (M* ∼ 1010.7 M⊙) as a function of colour and morphology. We use Galaxy Zoo to define three morphological classes of galaxies, namely
Star Formation Properties of a Large Sample of Irregular Galaxies
We present the results of Hα imaging of a large sample of irregular galaxies. Our sample includes 94 galaxies with morphological classifications of Im, 26 blue compact dwarfs (BCDs), and 20 Sm
