Welcome to my blog series, where I'll be sharing my exciting research journey exploring the mysteries of low-mass black holes and their connection to Gaia's observations! In this series, I will be sharing my experiences, insights, and discoveries as I delve into my research project. In this first post, I'm thrilled to unveil the details of my research topic and provide a glimpse into the excitement that lies ahead.


Introducing My Research Topic


In this first post, let's dive into the captivating world of black holes and uncover the significance of studying their low-mass counterparts.

Black holes have always fascinated scientists and the public alike with their immense gravitational pull and mysterious nature. However, one particular puzzle has caught the attention of researchers—the low-mass black hole problem. This intriguing phenomenon refers to the absence of black holes in a specific mass range, typically between the heaviest neutron stars and the lightest black holes, which are approximately 2 to 5 times the mass of our Sun.

Understanding the formation and properties of low-mass black holes is crucial for advancing our knowledge of astrophysics. It raises fundamental questions about the mechanisms involved in their creation and their role in the evolution of galaxies [Kreidberg et al., 2012]. To shed light on this enigma, I will conduct research using advanced computational simulations and analyze data from Gaia, a space observatory mission.

Gaia, a mission led by the European Space Agency (ESA), is designed to create a detailed 3D map of our Milky Way galaxy. By accurately measuring celestial objects' positions, distances, and motions, Gaia provides a wealth of data for researchers to explore. Recent groundbreaking detections, such as Gaia BH1 [El-Badry et al., 2023a] and Gaia BH2 [El-Badry et al., 2023b], have contributed valuable insights to the field, setting the stage for further investigations.

My research aims to delve into the dynamics of binary systems containing black holes. Binary star systems, where two stars orbit around a common center of mass, offer valuable insights into the formation and evolution of black holes. By utilizing N-body simulations, I can model the complex interactions and gravitational dynamics within these systems, considering factors such as initial conditions, mass transfer processes, and common-envelope evolution.

Through these simulations, I hope to address intriguing research questions, such as:

  1. What is the distribution of masses for black holes in the low-mass gap, as predicted by the simulations?

  2. How do the properties of binary systems containing low-mass black holes, including orbital parameters and mass ratios, impact the observed mass gap?

  3. What are the primary mechanisms responsible for the formation of low-mass black holes within binary systems?

  4. How do Gaia's observational sensitivities and biases influence the identification and understanding of low-mass black holes with detached luminous companions?

By gaining insights into these questions, I aim to contribute to the growing body of knowledge on black hole formation and bridge the gap in our understanding of low-mass black holes.
