At the beginning of your paper place your Mission Statement.

What are you mainly interested in exploring or researching and state how it could advance our knowledge of our universe. Regarding the object you will be studying (observing) explain the following: How is your object different or the same as other objects that have been observed? For example, if you are studying red giant stars, what is something new that we don’t know about them, compare/contrast them to other types of stars, what is unique about them, what is their life-cycle? Where is your object(s) located? For example, if they are quasars, speak to how we can determine their distance and age?

How have we determined how far away it is? If it is a galaxy, speak to its formation and evolution compared to other galaxies. Have any studies about dark matter or energy been done in relation to it? Based on what you want to study, will there need to be a spacecraft/telescope built? If a spacecraft is involved, define the type of instruments it will carry and technology used.

Speak to how the types of missions differ. For example, where you will place it in space, e.g. orbiting a certain point in space? Speak to the specific types of instruments you will employ on your craft and how they will help you accomplish your objective(s). Looking at other missions for examples will help you come up with ideas. Include what part of the spectrum you will be viewing in and how that will give you different information from other parts of the spectrum.

If it is a telescope, speak to if it will be built and what type (spectrum) it will be. If you are using an existing telescope, which one and what part of the spectrum will you be observing in? Include what type of telescope you are using (e.g. radio, optical, etc.), will you employ interferometry or other types of technology? Include what technology will be used?

Does it exist? Is someone currently developing it? For example, if it is a new kind of telescope, what kind of technical advances are being used to make it more powerful. Or if it is a spacecraft, what technology is going to propel your craft to its destination? Speak to how long you expect the mission/observations to last?

If you are employing a craft and visiting an object, how long will it take? Based on the orbit of your object, when do you want to visit it and why? What technology will you use to propel your craft? If you are observing an object with a telescope, how long will your observations be? For example, if you are observing variable stars or gamma-ray bursts, what will you base your observation length on?

What observation techniques will you employ? What might the general costs be? (This can be researched in detail later) For this you can compare your mission to others and make your best guess at the cost. Be sure to include your references used.

Paper For Above instruction

Introduction and Vision Statement

My primary research focus is on investigating the properties and life cycle of intermediate-mass black holes residing within dwarf galaxies. This exploration aims to deepen our understanding of black hole formation, growth, and their influence on galactic evolution. By studying these relatively under-explored objects, my goal is to contribute valuable insights into how supermassive black holes originate and evolve in the early universe, thereby advancing our knowledge of cosmic history and structure formation.

Object of Study and Its Significance

The target object for observation is the intermediate-mass black hole (IMBH) embedded within a nearby dwarf galaxy, such as the galaxy Holmi 1. IMBHs are characterized by masses ranging from 10³ to 10⁵ solar masses, situated between stellar-mass black holes and supermassive black holes. Unlike the well-studied supermassive black holes at galaxy centers, IMBHs are relatively elusive, with limited observational data. Understanding their properties, formation mechanisms, and role in galaxy evolution can shed light on the process of black hole seed formation in the early universe. Currently, IMBHs are suspected to form via dense stellar cluster collapses or direct gas cloud collapse, but direct evidence remains scarce. Their location in dwarf galaxies makes them accessible for observation and provides a unique test bed for models of black hole seed growth.

Location, Distance, and Formation

Holmi 1 is located approximately 12 million light-years away from Earth. Its relative proximity allows detailed observational studies using advanced telescopes. Distance measurements are based on redshift data and standard candles such as Cepheid variables and Type Ia supernovae. The formation of dwarf galaxies like Holmi 1 is believed to be a consequence of hierarchical merging processes, and their evolution provides insights into galaxy assembly. Studies have also linked the existence of dark matter halos to the formation and stability of these galaxies, with IMBHs potentially influencing their dynamical evolution.

Existing Technology and Future Mission Needs

To observe and analyze the IMBH in Holmi 1, a dedicated space-based observatory equipped with specific instruments is required. A proposed mission involves deploying a high-resolution X-ray and infrared telescope to detect accretion signatures and associated phenomena. The telescope would operate in the 0.1-10 keV X-ray range and near-infrared wavelengths. Technological advances such as adaptive optics, high-sensitivity detectors, and interference filtering will enhance observational capabilities. The mission is expected to last approximately five years, optimizing data collection during periods of predicted activity.

Mission Placement and Instrumentation

The spacecraft would be placed in a halo orbit around the Earth-Sun L2 Lagrange point to maintain a stable environment and minimal interference. The instruments include a pair of X-ray detectors derived from existing missions like Chandra but with improved sensitivity, and infrared cameras modeled after the James Webb Space Telescope instruments. Interferometric techniques could be employed to resolve the accretion disk features. Observations would focus on capturing variability in the X-ray emissions and infrared spectra to understand accretion processes and black hole characteristics.

Technology and Propulsion

The spacecraft would utilize ion propulsion technology for maneuvering, providing efficient and precise station-keeping. Given the mission duration and distance, the propulsion system ensures extended observational windows and flexible repositioning. The technology to propel the craft involves ion thrusters powered by solar energy, which are proven and reliable for deep-space missions.

Observation Techniques and Cost Estimate

The primary observing techniques include spectroscopic analysis, variability monitoring, and high-resolution imaging across the X-ray and infrared spectrum. Estimated costs for the mission are around $750 million, factoring in spacecraft construction, launch, operations, and data analysis, based on comparative analyses with similar missions like the Chandra X-ray Observatory and JWST. This investment is justified given the potential breakthroughs in understanding black hole seed formation and galactic evolution.

Conclusion

This proposed mission targeting an intermediate-mass black hole in a dwarf galaxy represents a significant step forward in astrophysics research. By employing advanced instrumentation and strategic spacecraft positioning, the mission will provide unique data to elucidate black hole formation pathways, their influence on galaxy dynamics, and the broader cosmic evolution. The insights gained will not only fill existing gaps in the current understanding but also pave the way for future research endeavors in studying black holes and their roles in shaping the universe.
