Galactic rotation dynamics in a new $$f({\mathcal {R}})$$ f ( R ) gravity model

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We propose to test the viability of the recently introduced $$f(\mathcal {R})$$ f ( R ) gravity model in the galactic scales. For this purpose we consider test particles moving in stable circular orbits around the galactic center.

Systematically Measuring Ultradiffuse Galaxies (SMUDGes). IV. Ultradiffuse Satellites of Milky Way Analogs

open access: yesThe Astronomical Journal, 2023
To better understand the formation of large, low-surface-brightness galaxies, we measure the correlation function between ultradiffuse galaxy (UDG) candidates and Milky Way analogs (MWAs).

The influence of galaxy surface brightness on the mass-metallicity relation [PDF]

open access: yes, 2015
We study the effect of surface brightness on the mass-metallicity relation using nearby galaxies whose gas content and metallicity profiles are available.

Spatial distribution of low-surface-brightness galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1994
Using redshift samples, we calculate the cross-correlation functions of LSB galaxies with normal galaxies in complete samples (i.e. CfA and IRAS), which enables us to compare directly the amplitudes and shapes of the correlation functions. For pair separations $r\gs 2\mpc$, we find that the shape is in agreement with that of the correlation functions ...

Searching in H i for Massive Low Surface Brightness Galaxies: Samples from HyperLeda and the UGC

open access: yesThe Astronomical Journal, 2023
A search has been made for 21 cm H i line emission in a total of 350 unique galaxies from two samples whose optical properties indicate they may be massive.

Understanding the Chemical Evolution of Blue Edge-on Low Surface Brightness Galaxies

open access: yesThe Astrophysical Journal, 2023
We present a sample of 330 blue edge-on low surface brightness galaxies (ELSBGs). To understand the chemical evolution of ELSBGs, we derived the gas-phase abundance and the [ α /Fe] ratio.

Fundamental Properties of the Dark and the Luminous Matter from the Low Surface Brightness Discs

open access: yesUniverse, 2021
Dark matter (DM) is one of the biggest mystery in the Universe. In this review, we start reporting the evidences for this elusive component and discussing about the proposed particle candidates and scenarios for such phenomenon.

Evidence for a Non-Expanding Universe: Surface Brightness Data From HUDF [PDF]

open access: yes, 2005
Surface brightness data can distinguish between a Friedman-Robertson-Walker expanding universe and a non-expanding universe. For surface brightness measured in AB magnitudes per angular area, all FRW models, regardless of cosmological parameters, predict

The dark and baryonic matter content of low surface brightness disk galaxies [PDF]

open access: yes, 1997
We present mass models of a sample of 19 low surface brightness (LSB) galaxies and compare the properties of their constituent mass components with those of a sample of high surface brightness (HSB) galaxies.We find that LSB galaxies are dark matter ...
