• Baryonic Masses and Properties of Gaseous Satellite Galaxies (2026) · The Astrophysical Journal · doi

  The need to include baryonic processes, such as stellar feedback and photoionization, in dwarf galaxy evolution models. The lack of understanding of the environment of dwarf galaxies and its impact on their baryonic content. The limited sensitivity of previous surveys to detect low-mass H i sources.

• Structural and dynamical properties of Tidal dwarf galaxies in the tails and bridge of the Guitar galaxy Arp 105 (2026) · Monthly Notices of the Royal Astronomical Society · doi

  There is a lack of understanding about the structural and dynamical properties of tidal dwarf galaxies. Prior studies have focused on classical dwarf galaxies, leaving a gap in our knowledge of tidal dwarf galaxies. The formation and evolution of tidal dwarf galaxies are not well understood.

• Structural and dynamical properties of Tidal dwarf galaxies in the tails and bridge of the Guitar galaxy Arp 105 (2026) · Monthly Notices of the Royal Astronomical Society · doi

  Further observations, particularly integral field spectroscopy and high-resolution 21 cm observations, are needed to better constrain the kinematics and improve our understanding of tidal dwarf galaxy formation. Studies of larger samples of tidal dwarf galaxies are necessary to confirm the results of this study. Theoretical models of tidal dwarf galaxy formation and evolution should be developed to explain the observed properties.

• Structural and dynamical properties of Tidal dwarf galaxies in the tails and bridge of the Guitar galaxy Arp 105 (2026) · Monthly Notices of the Royal Astronomical Society · doi

  The study is limited by the availability of observational data for tidal dwarf galaxies. The 2D GALFIT modeling has limitations due to the irregular shape of tidal dwarf galaxies. The spectral energy distribution modeling relies on assumptions about the stellar populations and dust content.

• Structural and dynamical properties of Tidal dwarf galaxies in the tails and bridge of the Guitar galaxy Arp 105 (2026) · Monthly Notices of the Royal Astronomical Society · doi

  The irregular shape of tidal dwarf galaxies makes it challenging to model their structural components. The lack of observational data for tidal dwarf galaxies limits our understanding of their properties. Theoretical models of tidal dwarf galaxy formation and evolution are needed to explain the observed properties.

• Testing the Stellar Feedback-driven Breathing Mode in Low-mass Galaxies with Gas Kinematics (2026) · The Astrophysical Journal · doi

  One of the challenges is the limited range of specific star formation rates in the observational sample. Another challenge is the need to correct for the mass dependence of gas velocity dispersion when comparing observations and simulations. The paper also notes that the diskiest galaxy in the sample, m11h, has a weaker relation between gas velocity dispersion and star formation rate.

• Ram-pressure signatures in the dwarf irregular galaxy Sextans B revealed by deep MeerKAT HI observations (2026) · Astronomy & Astrophysics · doi

  Further studies are needed to investigate the effects of environmental processes on the neutral gas distribution of dwarf galaxies in different environmental contexts. The use of hydrodynamical simulations and three-dimensional kinematic modelling can provide valuable insights into the evolution of dwarf galaxies.
