Mysterious Galactic Core Energy May Reveal a New Type of Dark Matter

Introduction

The enigmatic event at the center of our galaxy could potentially be caused by an alternative type of dark matter.

Dark matter, an elusive and unobservable substance potentially constituting 85% of the universe's mass, remains one of the most profound scientific pursuits.

New Findings on Dark Matter in the Milky Way

Pioneering research brings scientists a step closer to deciphering the enigma of dark matter, suggesting a novel candidate may drive unexplained chemical reactions in the Milky Way.

A Mystery in the Galactic Core: Positively Charged Hydrogen

Dr. Shyam Balaji, a Postdoctoral Research Fellow at King's College London and a lead author of the study, states: "At the heart of our galaxy lie vast clouds of positively charged hydrogen—an enduring mystery for decades, as hydrogen gas is typically neutral. What mechanism provides the energy necessary to dislodge electrons and create this ionization?"

The energy emission detected in this region of our galaxy indicate a persistent and dynamic energy source.

Could Dark Matter Be Lighter Than Previously Theorized?

Our data suggests that this phenomenon could be driven by a much lighter form of dark matter than currently theorized.

Challenges to the WIMP Model

The leading hypothesis for dark matter suggests it comprises Weakly Interacting Massive Particles (WIMPs), a class of particles that barely interact with ordinary matter, rendering them incredibly elusive.

Today's publication in Physical Review Letters suggests a paradigm shift, bringing renewed focus to a low-mass dark matter candidate that challenges the WIMP-dominated narrative.

A New Explanation: Low-Mass Dark Matter Collisions

According to the study, these lightweight dark matter particles may collide and annihilate, leading to the formation of charged particles capable of ionizing hydrogen gas.

Could Cosmic Rays or WIMPs Explain This Phenomenon?

Earlier explanations for this ionization process centered on cosmic rays—high-energy particles traversing the universe. However, observational data from the Central Molecular Zone (CMZ) suggest that the detected energy signatures are insufficient to be attributed to cosmic rays. Similarly, Weakly Interacting Massive Particles (WIMPs) do not appear capable of driving this phenomenon.

A Slower, Low-Mass Energy Source

The researchers concluded that the energy source driving the annihilation process must be:

• Slower than cosmic rays
• Possess a lower mass than WIMPs

A New Approach to Studying Dark Matter

Dr. Balaji stated, "The quest to uncover dark matter is one of the greatest pursuits in modern science, yet most experiments are conducted on Earth. By analyzing gas within the CMZ through a novel observational approach, we can directly investigate its origins. The data suggests that dark matter may be significantly lighter than previously assumed."

Implications for Galactic Phenomena

Unraveling the mystery of dark matter is a cornerstone of fundamental physics, yet most experiments remain Earth-bound, passively awaiting its detection. By examining the hydrogen gas at the heart of our Milky Way, the CMZ offers promising insights that may bring us closer to uncovering dark matter's true nature.

The 511-keV Emission Line and Dark Matter

This discovery could provide a unified explanation for broader galactic phenomena, including:

• The enigmatic 511-keV emission line observed at the Milky Way's core
• A distinctive X-ray signature that may also originate from low-mass dark matter interactions producing charged particles.
