Astronomy Research Paper

We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 ≤ z ≤ 0.62. The luminosity distances of these objects are determined by methods that employ relations between SN Ia luminosity and light curve shape. Combined with previous data from our High- z Supernova Search Team and recent results by Riess et al., this expanded set of 16 high-redshift supernovae and a set of 34 nearby supernovae are used to place constraints on the following cosmological parameters: the Hubble constant ( H0), the mass density (Ω M), the cosmological constant (i.e., the vacuum energy density, Ω Λ), the deceleration parameter ( q0), and the dynamical age of the universe ( t0). The distances of the high-redshift SNe Ia are, on average, 10%–15% farther than expected in a low mass density (Ω M = 0.2) universe without a cosmological constant. Different light curve fitting methods, SN Ia subsamples, and prior constraints unanimously favor eternally expanding models with positive cosmological constant (i.e., Ω Λ > 0) and a current acceleration of the expansion (i.e., q0 < 0). With no prior constraint on mass density other than Ω M ≥ 0, the spectroscopically confirmed SNe Ia are statistically consistent with q0 < 0 at the 2.8 σ and 3.9 σ confidence levels, and with Ω Λ > 0 at the 3.0 σ and 4.0 σ confidence levels, for two different fitting methods, respectively. Fixing a "minimal" mass density, Ω M = 0.2, results in the weakest detection, Ω Λ > 0 at the 3.0 σ confidence level from one of the two methods. For a flat universe prior (Ω M + Ω Λ = 1), the spectroscopically confirmed SNe Ia require Ω Λ > 0 at 7 σ and 9 σ formal statistical significance for the two different fitting methods. A universe closed by ordinary matter (i.e., Ω M = 1) is formally ruled out at the 7 σ to 8 σ confidence level for the two different fitting methods. We estimate the dynamical age of the universe to be 14.2 ± 1.7 Gyr including systematic uncertainties in the current Cepheid distance scale. We estimate the likely effect of several sources of systematic error, including progenitor and metallicity evolution, extinction, sample selection bias, local perturbations in the expansion rate, gravitational lensing, and sample contamination. Presently, none of these effects appear to reconcile the data with Ω Λ = 0 and q0 ≥ 0. byReferences

Astronomy can be defined as the science that is concerned with the material universe that extends beyond the atmosphere of Earth. As a result, the topic of astronomy deals with all that which extends beyond the context of which is most familiar to humans. While advances in telescopes, satellites and space travel have allowed humans to peer beyond the Earth, the degree to which this has occurred barely touches the surface of the vastness that is outer space. As a result of humans limited capacity for space observation and exploration, it can be stated that there is more that humans do not know about space than what is known with any degree of certainty. Much of the realms of astrophysics and the likes deals with theory and mathematical projections of these implications. As an interdisciplinary topic, astronomy is closely linked to mathematics, physics, chemistry and molecular biology. The theoretical nature of the subject and its propensity to challenge values held by human beings means that controversy often exists when unpopular conclusions are drawn.

46 Interesting Astronomy Research Paper Topics

Astronomy paper topics can be quite involved and intimidating; particularly to students outside of the discipline. For non majors, exploration of astronomy topics can include the utilization of other lenses of inquiry. For example, history majors could select historical analysis of astronomy topics like “Early Astronomers: Ptolemy, Aristotle, Copernicus and Galileo.” Similarly, literature majors could choose an astronomy related topic like, “Representations of Space Travel in Science Fiction: Ray Bradbury and Arthur C. Clarke.” Both of these examples would involve exploring astronomy through an interdisciplinary perspective. For pure students of astronomy or students of astrophysics, examining specific phenomena like dark matter or wormholes could be a better course of action.

When selecting a topic, students should first determine the lens of inquiry related to their respective field of study or interest and second, students should have realistic expectations of the degree to which a topic can be explored in the project size established. The amount of material that can be covered in a 100 page dissertation would be much more extensive than that which could be covered in a rudimentary three page discussion. Below is a list of some topics that fall within the scope of inquiry specific to astronomy topics. This list only is a small sampling of the many directions in which a student could go for their exploration of an astronomy related topic. The staff at can complete a project on any of the below listed topics or this list can be used to help inspire original ideas for student inquiry.
