What is the mass-to-light ratio of the M94 galaxy?
Best insight from top research papers
The mass-to-light ratio of the M94 galaxy is significant, as indicated by various observations. The HI observations with the FAST telescope revealed a total HI mass of (6.51±0.06)×10^8 M⊙, which is 63.0% more than previously observed, suggesting a substantial mass content in the galaxy . Additionally, multi-wavelength analysis showed that the outer disk of M94 contains about 23% of the total stellar mass budget of the galaxy, indicating a significant mass contribution from this region . These findings imply that M94 has a considerable mass relative to its light output, highlighting an intriguing mass-to-light ratio in this galaxy.

How much mass is in the interstellar medium compared to the mass of stars?5 answersThe interstellar medium (ISM) contains orders of magnitude more mass than all the stars combined. It is the prime component of the baryonic universe. The mass of the ISM is significantly greater than the mass of stars.
What would be the implications of a photon having mass?4 answersThe implications of a photon having mass would include a dispersion of electromagnetic waves in free space and the occurrence of a longitudinal polarization state. Deviations to standard formulas would occur at energies comparable to the mass energy. The mass of the photon would cause a force at the contact point of reflection, resulting in a slight deviation of the photon from its path after reflection. This deviation would depend on the angle of polarization plane of laser light with respect to the reflecting mirror. The mass of the photon would be located off-center, away from the center of the photon, explaining the wave-particle duality of electromagnetic radiations. The feasibility and calculation of the values of the density and mass of electromagnetic particles would be proposed, with a calculation showing that the photon must have mass. The mass of the photon would cause modifications to the Coulomb law, gauge invariance, and charge conservation. The PoE mass of present-day photons, calculated within the Scale-Symmetric Theory, is about 27 orders of magnitude lower than the rest mass of the electron and is invariant.
Does light has mass?4 answersLight does not have mass. According to Einstein's theory of relativity, light must have zero rest mass in order to propagate at the speed of light. Although light carries momentum and energy, it does not have inertial mass. This means that by the principle of equivalence, light also does not have gravitational mass. Experimental observations have confirmed that photons, which are particles of light, do not have rest mass. Additionally, measurements of the behavior of light reflected from a smooth surface indicate that light has no mass but can mimic mass. Therefore, it can be concluded that light is a massless particle.
What are extreme mass ratio inspirals?5 answersExtreme mass ratio inspirals (EMRIs) are systems that involve a small compact object, such as a black hole or a boson star, orbiting around a much larger and more massive object, such as a supermassive black hole. These systems are of great interest in the study of black hole spacetimes and gravitational wave measurements. EMRIs can provide valuable information about the dynamics of black holes and the spacetime around them. They can also be used to accurately measure the properties of black holes, such as their mass and spin. The dynamics of EMRIs near orbital resonances have been analyzed using the action-angle formalism, which has led to the derivation of effective resonant Hamiltonians that describe the motion of the resonant degree of freedom. Numerical simulations have demonstrated the presence of orbital chaos and transitions between different branches of rotational orbits. These findings contribute to the understanding of EMRI dynamics and pave the way for precise measurements of black hole spacetimes.
What is the stoichiometric ratio for hydrogen?3 answersThe stoichiometric ratio for hydrogen is not explicitly mentioned in the abstracts provided. However, stoichiometry is a fundamental concept in chemistry that refers to the ratios of products and reactants in any chemical reaction. In the context of hydrogen, stoichiometry is important in both chemical reactions and biochemical processes. Using the correct stoichiometric amount of hydrogen as a reactant will yield the maximum amount of product under the proper thermodynamic and kinetic conditions.
What is the goal of prey predator mass ratio in ecology ?5 answersThe goal of prey-predator mass ratio in ecology is to understand the structure and dynamics of food webs. It is a critical parameter for capturing the complex patterns of feeding links among species and individuals in a simplified way. The mass ratio can be defined at different biological scales, such as from individuals to communities, and may vary with biological factors such as species identity and body mass. The empirical estimation of prey-predator mass ratio is challenging due to scale-dependence and the need to consider determinants such as species identity and body mass. Future research should focus on accounting for scale dependence and associated determinants to improve the utility of prey-predator mass ratio as a widely applicable tool.
